README

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
  * catch, throw, unwind-protect
  * 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:
  * 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
  * flet, lexical-let and/or optional lexical binding as extensions

Extensions over original elisp:
  * (guile-ref module symbol) construct to build a (@ module symbol) from elisp
