JeffBezanson	332235231c	changing semantics to respect lexical scope more strictly; now ... anything can be shadowed by closer nested variables fixing bugs in let-syntax and expanding optional arg default values improving expansion algorithm on internal define some small optimizations to the compiler maintaining interpreter for bootstrapping	2009-08-12 04:56:32 +00:00
JeffBezanson	15c8cb327d	finishing initial implementation of keyword arguments ... fixing up interpreter so it can be used for bootstrapping again removing let/copyenv optimization because it really didn't seem to help much	2009-08-02 04:06:07 +00:00
JeffBezanson	c19aaeabd6	keeping track of function names, printing nice stack traces ... changing default bootstrap process to use VM instead of interpreter fixing bug where only a fixnum could index a vector merging equal.c into the main compilation unit	2009-07-10 04:17:39 +00:00
JeffBezanson	1259c17837	updating interpreter to work better for bootstrapping ... adding program mkboot0, which can be run in the interpreter to compile source files into a stage-0 boot image.	2009-04-23 00:55:03 +00:00
