Recognize and expand macros (albeit not yet with proper lexical + scoping: local bindings are not able to shadow a macro). + (eval_init): Protect top_mb from GC and initialize it. + Intern new symbols defmacro, macro-time, and :whole. + Register defmacro operator in op_table. + + * match.h (env_k): Added declaration for existing external variable. + +2014-02-15 Kaz Kylheku <kaz@kylheku.com> + Bugfix: parameters of defun were not being treated by expander. They need to be since they can contain evaluable initforms for default arguments. Ditto with lambda; lambda parameters were being treated |
