Illuminated Macros
summary
Proposal defines sequence expressions (a regex-like matcher over Clojure values) plus a parser function parse-forms and a macro wrapper defsyntax that generate complete grammars, machine-readable docs and pinpointed syntax errors; example reproduces full let and defn grammars and a colorized syn-do printer. Grammars support recursion, captures/recaps for arbitrary computation, and composable rule reuse. Prototype emits better error locations and expected tokens; expansion tracing and final output-generation examples remain planned but not yet shipped.
