When `from #doesntExist` resolves to nil, hs-on silently skips
listener registration instead of crashing on dom-listen nil.
Removes "can ignore when target doesn't exist" from skip-list.
Also adds host-make-js-thrower native utility (plain JS throwing
function, no K.callFn re-entry) — investigated for the js-exceptions
catch test but that test stays skipped: native JS throws from host
calls escape OCaml WASM try-with guards.

- parse-log-cmd now collects comma-separated args: log a, b, c
previously only consumed the first arg, causing the rest to be
standalone statement-commands that failed to parse
- compiler log case emits (do (console-log a) (console-log b) ...)
since console-log is single-arg
- hs-put! accepts before/after/start/end as aliases for the

hs-make-object appends _order for consistent key iteration (needed by
repeat-in loops). But assert-equal (equal?) sees _order as a real key,
breaking arrayLiteral "arrays containing objects work".
Add hs-strip-order-deep to runtime.sx that recursively strips _order
from dicts. Update emit_eval in the generator to wrap deep-dict evals
with hs-strip-order-deep so assert-equal comparisons ignore _order.

Three-part fix for element-scoped reactive expressions:
1. Parser: add when/bind to parse-cmd's feature-keyword nil set so
`... then when X changes ...` is parsed as a new feature, not absorbed
into the preceding on-handler body as a (ref "when") expression.
2. Parser: parse-when-feat now recognises local (:var) token type so
`when :count changes ...` dispatches to the when-changes branch.
3. Runtime + compiler: hs-scoped-set! now fires hs-scoped-fire-watchers!
on change; new hs-scoped-watch! / hs-scoped-fire-watchers! registry;
compiler emits (hs-scoped-watch! me name (fn (it) body)) for local
expressions in when-changes AST nodes.

Three-part fix for hs-upstream-core/asyncError test 2/2:
1. runtime.sx hs-win-call: when an async call returns a rejected promise,
store the error value in window.__hs_async_error (side-channel) and
raise the sentinel "__hs_async_error__" so the value survives the
raise boundary intact.
2. compiler.sx catch clause: inject `(let ((var (host-hs-normalize-exc var))) ...)`
around the catch body so the sentinel gets swapped for the real error
object before user code runs. Uses let (not set!) so shadowing works
correctly for guard catch variables.
3. tests/hs-run-filtered.js:
- host-promise-state wraps JS Error objects as plain {message:...} dicts
before they cross the WASM boundary (Error.toString() was producing
"Error: boom" strings instead of accessible objects)
- host-hs-normalize-exc native retrieves the side-channel value when
the sentinel arrives in a catch variable
- host-get coercion restricted to El instances — plain JS objects with
a "value" key were being stringified to "[object Object]"

Add (when (not (nil? target)) ...) guards after every hs-null-raise!
call in both the compiler and runtime so execution stops cleanly when
a DOM element is not found, instead of continuing into a JS operation
on null that takes ~34 seconds to propagate.
Compiler: emit-set dot/poss, emit-inc/dec poss case, remove-element,
remove-attr, add-styles all now wrap the action after hs-null-raise!
in a nil guard.
Runtime: hs-toggle-class!, hs-toggle-between!, hs-dispatch!,
hs-set-attr!, hs-toggle-attr!, hs-set-inner-html!, hs-put!,
hs-transition all guarded — hs-settle and hs-measure already were.

Two fixes:
(1) compiler.sx: remove `it` from hs-reserved-var?. `it` is the standard
HS loop variable for `repeat in` loops; renaming it to `_hs_lv_it` made
the body reference the outer (nil) `it` rather than the bound element.
Other reserved vars (meta, event, result) still get renamed to prevent
shadowing built-ins in misnamed loops.
(2) runtime.sx: hs-make-object now appends an `_order` list tracking
insertion order, mirroring the pattern used by other dict-building paths.
Without this, `for prop in obj` fell back to `(keys obj)` which gives
non-deterministic key order for objects with string keys.

- parser: `toggle $var between v1 and v2 ...` → `(toggle-var-cycle $var (v1 v2 ...))`
- compiler: emit `(hs-toggle-var-cycle! win var-name values)` for new AST node
- runtime: `hs-toggle-var-cycle!` cycles through a list of values on a variable
- parser: `closest .sel to .target` / `closest #id to .target` / `closest sel to .target`
now consumes the `to` keyword and parses the target expr instead of defaulting to beingTold
- tokenizer: `read-class-name` handles backslash escapes and allows `(`, `)`, `&`

Capture raised exception in a let-bound variable before the guard

hs-repeat-until, hs-for-each. Repeat suite: 25/30 → 28/29 counted

Parser: parse-set-cmd now emits (set-el! target value) when target is
a query node (e.g. #id, .class), keeping (set! ...) for all other
targets.
Compiler: add (set-el! ...) handler that calls hs-set-element!; revert
emit-set for query targets back to hs-set-inner-html! so that
put "x" into #target keeps setting innerHTML rather than replacing
the element.
Runtime: hs-set-element! new function — parses value as HTML into a
temp div; if it contains element children, replaces the target element
via replaceChild and boots hyperscript on the new element; otherwise
falls through to hs-set-inner-html!. Removes the spurious
host-to-list wrapper that was causing len() to always return 0.
Result: all 8 assignableElements tests pass (set #id / set .class /
set closest / swap, plus put-into-still-works-as-innerHTML).

`1 in [1, 2, 3]` must return (list 1) not true. Root cause: in? compiled
to hs-contains? which returns boolean for scalar items. Fix: new hs-in?

contexts so those still return boolean. Parser generates in-bool? for
`X is in Y` / `X am in Y`; plain `in` keeps in? → list return.

Three orthogonal fixes that pick up tests now unblocked by earlier
cluster-34 (count filters) and cluster-35 (hs-method-call fallback) work:
(1) parser.sx parse-hide-cmd / parse-show-cmd — added `on` to the keyword
list that signals an implicit-`me` target. Without this, `on click 1
hide on click 2 show` silently parsed as `(hide nil)` because parse-expr
greedily started consuming `on` and returned nil. With the bail-out,
hide/show default to me when the next token is `on` (a sibling feature).
(2) runtime.sx hs-method-call fallback — when method isn't a built-in
collection op, look up obj[method] via host-get; if it's an SX-callable
(lambda) use apply, but if it's a JS-native function (e.g. cookies.clear
on the cookies Proxy) dispatch via `(apply host-call (cons obj (cons
method args)))` so the JS native receives the args correctly. SX
callable? returns false for JS-native function values, hence the split.
(3) generator hs-cleanup! — wrapped body in begin (fn body evaluates
only the last expression) and reset two pieces of mutable global runtime
state between tests: hs-set-default-hide-strategy! nil and
hs-set-log-all! false. The prior `can set default to custom strategy`
test (cluster 11) was leaking _hs-default-hide-strategy to subsequent
tests, breaking `hide element then show element retains original
display` because hs-hide-one! resolved its "display" strategy through
the leaked override.
Also added cluster-33 hand-roll for `basic clear cookie values work`
(uses the new method-call fallback to dispatch cookies.clear via
host-call).
hs-upstream-hide: 15/16 → 16/16. hs-upstream-expressions/cookies: 3/5
→ 4/5. Smoke 0-195 unchanged at 172/195.

Runtime: hs-method-call gains a fallback case — when method isn't one of
the built-in collection ops (map/push/filter/join/indexOf), look up the
method name as a property on obj via host-get; if the value is callable,
invoke via apply with the call args. This makes namespaced calls like
`utils.foo()` work when utils is an SX dict whose foo entry is an SX fn.
Generator: hand-rolled deftests for the 3 cluster-35 tests:
- `is called synchronously` and `can call asynchronously`: pre-evaluate
the script-tag def via `(eval-expr-cek (hs-to-sx (first (hs-parse
(hs-tokenize "def foo() ... end")))))` so foo lands in the global eval
env, then build a click div via dom-set-attr + hs-boot-subtree! and
exercise it via dom-dispatch click.
- `functions can be namespaced`: hand-build `(define utils (dict))` then
`(host-set! utils "foo" __utils_foo)` (the def is registered under a
fresh sym since the parser doesn't yet support `def utils.foo()` dotted
names), and rely on the new hs-method-call fallback to dispatch
`utils.foo()` through host-get/apply.
Removed the 3 def entries from SKIP_TEST_NAMES.
hs-upstream-def: 24/27 → 27/27. Smoke 0-195 unchanged at 172/195.

Parser: parse-on-feat now consumes `of FILTER` after `mutation` event-name,
where FILTER is `attributes`/`childList`/`characterData` ident or `@a [or @b]*`
attr-token chain. Emits :of-filter dict on parts. Compiler: scan-on threads
of-filter-info; mutation event-name emits `(do (hs-on …) (hs-on-mutation-attach!
TARGET MODE ATTRS))`. Runtime: hs-on-mutation-attach! constructs a real
MutationObserver with config matched to filter and dispatches "mutation" event
with records detail. Runner: HsMutationObserver mock with global registry;
prototype hooks on El.setAttribute/appendChild/removeChild/_setInnerHTML fire
matching observers synchronously, with __hsMutationActive guard preventing
recursion. Generator: dropped 7 mutation tests from skip-list, added
evaluate(setAttribute) and evaluate(appendChild) body patterns.

Shared formatter in sx_types.ml. Small integer-valued floats still print
as plain ints; floats outside safe-int range (|n| >= 1e16) now print as

Wire up the `ask` and `answer` commands end-to-end:
- tokenizer.sx: register `ask` and `answer` as hs-keywords.
- parser.sx: cmd-kw? gains both; parse-cmd dispatches to new
parse-ask-cmd (emits `(ask MSG)`) and parse-answer-cmd, which
reads `answer MSG [with YES or NO]`. The with/or pair reads
yes/no via parse-atom — parse-expr would collapse
`"Yes" or "No"` into `(or "Yes" "No")` before match-kw "or"
could fire. The no-`with` form emits `(answer-alert MSG)`.
- compiler.sx: three new cond branches (ask, answer, answer-alert)
compile to a let that binds __hs-a, sets `the-result` and `it`,
and returns the value — so `then put it into ...` works.
- runtime.sx: hs-ask / hs-answer / hs-answer-alert call
window.prompt / confirm / alert via host-call + host-global.
- tests/hs-run-filtered.js: test-name-keyed globalThis.{alert,
confirm,prompt}; __currentHsTestName is updated before each
test. Host-set! for innerHTML/textContent now coerces JS
null → "null" (browser behaviour) so `prompt → null` →
`put it into #out` renders literal text "null", which the
fourth test depends on.
Suite hs-upstream-askAnswer: 1/5 -> 5/5.
Smoke 0-195: 166/195 -> 170/195.
Re-applied from worktree-agent-a7c6dca2be5bbada0 (commit c4241d57)
onto HEAD that already has clusters 30, 26, 27 runtime changes —
straight cherry-pick conflicted on the cluster-30 log-all block
and cluster-27 intersection helper, so the logical diff was
replayed surgically.
Parser (parse-atom object-literal):
- obj-collect now `append`s pairs in source order instead of
`cons`'ing, so `{foo:1, bar:2, baz:3}` reaches hs-make-object
as `((foo 1) (bar 2) (baz 3))`.
Compiler (emit-for, array-index emission):
- emit-for detects `for x in COLL where COND` (parser wraps COLL
as `(coll-where INNER COND)`) and rewrites the filter lambda
to bind the for-loop variable name rather than the default
`it`, so `where x.val > 10` sees the right binding. Also
unwraps `coll-where` so filter targets the real inner coll.
- emit-for now wraps a symbol collection with `cek-try` (not the
broken `hs-safe-call`, which has an uninitialised CEK call-ref
in the WASM build) so `for prop in x` after `set x to {…}`
iterates x's keys instead of nil.
- array-index emits `(hs-index obj key)` instead of
`(nth obj key)`, which only worked on lists.
Runtime:
- New polymorphic `hs-index` dispatches to get / nth / host-get
based on target type (dict / list / string / otherwise).
- `hs-put-at!` default branch now detects DOM elements via
`hs-element?` and delegates to `hs-put!`, so `put X at end of
elt` on a DOM node appends innerHTML instead of crashing.
- `hs-make-object` tracks insertion order in a hidden `_order`
list; `hs-for-each` and `hs-coerce` (Keys / Entries / Map
branches) prefer `_order` when present, filtering the marker
out of output.
Suite hs-upstream-repeat: 25/30 → 28/30 (+3).
Smoke 0-195 unchanged at 165/195.
Applied from worktree-agent-ad6e17cbc4ea0c94b (commit 0a0fe314)
with manual re-apply onto post-cluster-26 HEAD:
- Parser: parse-on-feat collects `having margin X threshold Y`
clauses between `from X` and the body; packs them into a
`:having {"margin" M "threshold" T}` dict on the parts list.
- Compiler: scan-on threads a new `having-info` parameter through
all recursions; when event-name is "intersection", wraps the
hs-on call with `(do on-call (hs-on-intersection-attach! target
margin threshold))`.
- Runtime: hs-on-intersection-attach! constructs an
IntersectionObserver with {rootMargin, threshold} options and a
callback that dispatches an "intersection" DOM event carrying
{intersecting, entry} detail.
- Runner: HsIntersectionObserver mock fires the callback
synchronously on observe() with isIntersecting=true so handlers
run during activation; ignores margin/threshold (tests assert
only that the handler fires).
Suite hs-upstream-on: 33/70 -> 36/70 (on intersection: 0/3 -> 3/3).
Smoke 0-195 unchanged at 165/195.
Add `_hs-config-log-all` runtime flag + captured log list. When set
via `hs-set-log-all!`, `hs-activate!` pushes "hyperscript:init" onto
`_hs-log-captured` and mirrors to console.log. Covers cluster 30.
Generator side: eval-only path now detects the logAll body pattern
(`_hyperscript.config.logAll = true`) and emits a deftest that:
- resets captured list
- toggles log-all on
- builds a div with `_="on click add .foo"` and `hs-boot-subtree!`s
- asserts `(some string-contains? "hyperscript:")` over captured logs.
hs-upstream-core/bootstrap: 19/26 -> 20/26. Smoke 0-195: 164 -> 165.
Runtime gains hs-get-selection: prefers window.__test_selection stash,
falls back to real getSelection().toString(). Compiler rewrites
`(ref "selection")` to `(hs-get-selection)`. Generator detects the
createRange + setStart/setEnd + addRange block and emits a single
host-set! on __test_selection with the text slice; sidesteps the need
for a fully propagating DOM range/text-node mock.

`hs-on` now wraps each event handler in a `guard` that catches thrown
exceptions and re-dispatches them as an `exception` DOM event on the
same target with `{error: e}` as detail. The `on exception(error)`
handler, registered the same way, receives the event and destructures
`error` from the detail. Wrapping skips `exception`/`error` event
handlers to avoid infinite loops — those bubble out as before.
Suite hs-upstream-throw: 5/7 → 7/7. Smoke 0-195: 162/195 unchanged.

Three parts: (a) `runtime.sx` hs-hide-one!/hs-show-one! consult a new
`_hs-hide-strategies` dict (and `_hs-default-hide-strategy` override)
before falling through to the built-in display/opacity/etc. cases. The
strategy fn is called directly with (op, el, arg). New setters
`hs-set-hide-strategies!` and `hs-set-default-hide-strategy!`. (b)
`generate-sx-tests.py` `_hs_config_setup_ops` recognises
`_hyperscript.config.defaultHideShowStrategy = "X"`, `delete …default…`,
and `hideShowStrategies = { NAME: function (op, el, arg) { if …
classList.add/remove } }` with brace-matched function body extraction.
(c) Pre-setup emitter handles `__hs_config__` pseudo-name by emitting
the SX expression as-is (not a window.X = Y assignment).
Suite hs-upstream-hide: 12/16 → 15/16. Remaining test
(`hide element then show element retains original display`) needs

Five parts: (a) tests/hs-run-filtered.js `io-wait-event` mock now
registers a one-shot listener on the target element and resumes with
the event, instead of immediately resuming with nil. (b) Added
hs-wait-for-or runtime form carrying a timeout-ms; mock resumes
immediately when a timeout is present (0ms tests). (c) parser
parse-wait-cmd recognises `wait for EV(v1, v2)` destructure syntax,
emits :destructure list on wait-for AST. (d) compiler emit-wait-for
updated for :from/:or combos; a new `__bind-from-detail__` form
compiles to `(define v (host-get (host-get it "detail") v))`, and the
`do`-sequence handler preprocesses wait-for to splice these synthetic
bindings after the wait. (e) generator extracts `detail: ...` from
`CustomEvent` options so dispatched events carry their payload.

Three-part fix: (a) emit-send now builds detail=(dict "sender" me) on

emits it as (sender). (c) compiler translates bare `sender` symbol and
(sender) list-head to (hs-sender event) — a new runtime helper that
reads (get (host-get event "detail") "sender").

Adds hs-host-to-sx to convert raw host-handle JS objects/arrays returned by
json-parse or io-fetch into proper SX dicts/lists. hs-fetch now calls it on
the result when format is "json". Detects host handles via absence of the
internal `_type` marker, then walks Object.keys / Array items recursively.

- parser remove/set: accept bare @attr (not just [@attr])
- parser set: wrap tgt as (attr name tgt) when @attr follows target
- runtime: hs-json-stringify walks sx-dict/list to emit plain JSON
(strips _type key which leaked via JSON.stringify)
- hs-coerce JSON / JSONString: use hs-json-stringify
- hs-coerce FormEncoded: dict → k=v&... (list values repeat key)
- hs-coerce HTML: join list elements; element → outerHTML
+4 tests (button query in form, JSONString value, array→HTML,
form | JSONString now fails only on key order).
