Guile's Emacs Lisp compiler
===========================
This is more or less a lot of work in progress. Here are some notes as well
as status information.
Already implemented:
* progn, prog1, prog2
* if, cond, when, unless
* not, and, or
* referencing and setting (setq) variables
* while, dotimes, dolist
* let, let*
* lambda expressions, function calls using list notation
* some built-ins (mainly numbers/arithmetic)
* defconst, defvar, defun
* macros
* quotation and backquotation with unquote/unquote-splicing
Especially still missing:
* catch/throw, unwind-protect
* real elisp reader instead of Scheme's
* set, makunbound, boundp functions
* more general built-ins
* funcall and apply functions
* fset & friends, defalias functions
* advice?
* defsubst and inlining
* need fluids for function bindings?
* recursive macros
* anonymous macros
Other ideas and things to think about:
* %nil vs. #f/'() handling in Guile, possibly get rid of setting empty rest
arguments to %nil
* don't ensure-fluids for variables known to be let- or argument-bound
* or, perhaps, get rid of ensure-fluids over all but rather scan all code for
variables and create all needed fluids beforehand
