This is in anticipation of future features. + + * lib.c (expr_s): New symbol variable. + (obj_init): expr_s initialized. + + * lib.h (expr_s): Declared. + + * match.c (dest_bind): Now takes linenum. Tests for the meta-syntax + denoted by the system symbols var_s and expr_s, and throws an + error. + (eval_form): Similar error checks added. Also, hack: do not add + file and line number to an exception which begins with a '(' + character; just re-throw it. This suppresses duplicate line + number addition when this throw occurs across some nestings. + (match_files): Updated calls to dest_bind. + + * parser.l (yybadtoken): Handle new token kind, METAVAR and METAPAR. + (grammar): Refactoring among patterns: TOK broken into + SYM and NUM, NTOK introduced, unused NUM_END removed. + Rule for @( producing METAPAR in nested state. + + * parser.y (METAVAR, METAPAR): New tokens. + (meta_expr): New nonterminal. + (expr): meta_expr and META_VAR productions handled. + +2011-10-06 Kaz Kylheku <kaz@kylheku.com> + Renaming the currying combinators according to new scheme. * lib.c (bind2): Function renamed to curry_12_2. |
