[Coco] [CoCo] Re: Basic Lisp

[J Arcane]

It's on Github at https://github.com/jarcane/heresy but it doesn't quite
work at the moment and I've yet to write proper docs for it. I've got most
of the important syntax defined now, and you can load it and run stuff with
them in the REPL, but I haven't been able to get it working as a library or
#lang module, and I'm having a hell of a time figuring out why.
