Andy Wingo 5a0132b337 a different tack for syncase macro representation ... * libguile/macros.c (macro_print): Show syntax-case bindings, if present. (macro_mark): Mark the extra two words if they're there. (scm_make_syncase_macro, scm_make_extended_syncase_macro): OK! A new take at the "how do we represent syncase macros in Guile" problem. Whereas we need a disjoint type, but would like it to be compatible with old predicates (e.g. `macro?'), and need to be able to extend existing syntax definitions (e.g. `cond'), let's add a bit to macros to indicate whether they have syncase macro bindings or not, and a fourth macro type for native syncase macros. (scm_macro_type): Return 'syntax-case for native syntax-case macros. Note that other macro types may have syntax-case bindings. (scm_macro_name): Return #f if the transformer is not a procedure. (scm_syncase_macro_type, scm_syncase_macro_binding): New accessors for the syncase macro bindings. * libguile/macros.h: Add API for syncase macros. * module/ice-9/boot-9.scm (module-define-keyword!): Adapt to use syncase macros, though they are not yet used. Reorder other syncase API. * module/ice-9/psyntax.scm (chi-expr): Fix syntax-violation invocation.		2009-04-29 00:38:12 +02:00
