- [x] Reader: list, dotted pair, quote `'`, function `#'`, quasiquote `` ` ``, unquote `,`, splice `,@`, vector `#(…)`, uninterned `#:foo`, nil/t literals
- [ ] Parser: lambda lists with `&optional` `&rest` `&key` `&aux` `&allow-other-keys`, defaults, supplied-p variables

- 2026-04-25: Phase 1 lambda-list parser — 31 new tests, 172 total green. `cl-parse-lambda-list` in `parser.sx` + `tests/lambda.sx`. Handles &optional/&rest/&body/&key/&aux/&allow-other-keys, defaults, supplied-p. Key gotchas: `(when (> (len items) 0) ...)` not `(when items ...)` (empty list is truthy); custom `cl-deep=` needed for dict/list structural equality in tests.
- 2026-04-25: Phase 1 reader/parser — 62 new tests, 141 total green. `lib/common-lisp/parser.sx`: cl-read/cl-read-all, lists, dotted pairs, quote/backquote/unquote/splice/#', vectors, #:uninterned, NIL→nil, T→true, reader macro wrappers.
- 2026-04-25: Phase 1 tokenizer — 79 tests green. `lib/common-lisp/reader.sx` + `tests/read.sx` + `test.sh`. Handles symbols (pkg:sym, pkg::sym), integers, floats, ratios, hex/binary/octal, strings, #\ chars, reader macros (#' #( #: ,@), line/block comments. Key gotcha: SX `str` for string concat (not `concat`), substring-based read-while.
