giles	0e426cfea8	cl: Phase 4 CLOS complete — generic functions, multi-dispatch, method qualifiers, 437/437 tests ... - lib/common-lisp/clos.sx (27 forms): class registry (8 built-in classes), defclass/make-instance/slot-value/slot-boundp/change-class, defgeneric/defmethod with :before/:after/:around, clos-call-generic (standard combination: sort by specificity, fire befores, call primary chain, fire afters reversed), call-next-method/next-method-p, with-slots, deferred accessor installation - lib/common-lisp/tests/clos.sx: 41 tests (class-of, subclass-of?, defclass, make-instance, slot ops, inheritance, method specificity, qualifiers, accessors, with-slots, change-class) - lib/common-lisp/tests/programs/geometry.sx: 12 tests — intersect generic dispatching on geo-point×geo-point, geo-point×geo-line, geo-line×geo-line, geo-line×geo-plane (multi-dispatch by class precedence) - lib/common-lisp/tests/programs/mop-trace.sx: 13 tests — :before/:after tracing on area and describe-shape generics, call-next-method in circle/rect - eval.sx: dynamic variables — cl-apply-dyn saves/restores global slot for specials; cl-mark-special!/cl-special?/cl-dyn-unbound; defvar now marks specials; let/let* rebind via cl-apply-dyn; 8 new tests (182 eval total) - conformance.sh + test.sh: Phase 4 suites wired in - plans/common-lisp-on-sx.md: Phase 4 + dynamic variable boxes ticked Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-05-05 11:38:37 +00:00
giles	85911d7b84	cl: Phase 3 interactive-debugger — *debugger-hook* pattern, 7 tests (143 total) ... cl-debugger-hook global (nil = default), cl-invoke-debugger walks the hook, cl-error-with-debugger routes unhandled errors through the hook, and make-policy-debugger builds a hook from a (fn (condition restarts) name) policy function. Tests: hook receives condition, policy selects use-zero/abort restarts, compute-restarts visible inside hook, handler wins before hook fires, infinite-recursion guard. Wired into test.sh program suite runner. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-05-05 11:17:57 +00:00
giles	ab66b29a74	cl: Phase 3 classic programs — restart-demo (7 tests) + parse-recover (6 tests) ... restart-demo.sx: safe-divide with division-by-zero condition, use-zero and retry restarts. Demonstrates handler-bind invoking a restart to resume computation with a corrected value. parse-recover.sx: token parser signalling parse-error on non-integer tokens, skip-token and use-zero restarts. Demonstrates recovery-via- restart and handler-case abort patterns. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-05-05 11:16:35 +00:00
