* First things: ** TODO Remove kw_macro We determine what's a macro based on "syntax-rules" (so we need to make sure that's always there) ** DONE (let) doesn't work at all ** Should (let) include an implicit (begin)? s9fes seems to do it ** TODO need an "unspecified" type? ** TODO (display) should return unspecified ** TODO implement (pair) Pairs should be preserved, I think Also, it should _only_ be pairs, nothing more. ** TODO (define) needs to support function definitions Right now you need to use lambda ** DONE (cons) doesn't work This appears to work, now, but not with a pair * Read ** macro "transformers" should be "clauses" Which themselves consist of "pattern" -> "template" ** DONE "quote" and "quasiquote" symbols not supported The shortcuts work, but not the keywords ** TODO switch "define-syntax" to "let-syntax" format I think 'let-syntax' is the better building block * Eval * Print * Things to watch for ** fold-case directives (2.1) They affect the port for all remaining activity on that port. ** bar identifiers (2.2) How do they work? |some id|? ** yet another comment? (2.2) How to handle #; * Macro expansion ** Workflow - Take pattern - substitute args for non-literals (in order) - compare result with ast - if it's a match, return a lamba with the matching args and the transformer ...but what about ellipsis??
