A sort-of-a-lisp extracted from a previous project.
Originally intended to be used as a configuration language. Designed to be easy to grok and fast. It doesn't have a garbage collector but instead frees everything when the environment is destroyed. Uses lists instead of cons cells internally.
Supports lambdas, special forms, recursion, debugging, tracing, defining functions and variables, etc.
