sctb/lumen: A Lisp for Lua and JavaScript

Lumen is a very small, self-hosted Lisp for Lua and JavaScript. It provides a flexible compilation environment with an extensible reader, macros, and extensible special forms, but otherwise attempts to match the target runtime environment as closely as possible. You can get started by running bin/lumen on a machine with Node.js, Lua, or LuaJIT installed.
