Lithp is a relatively simple minded attempt at writing a lisp dialect. Every language element (macros, functions, lambdas) are first class members of the language. It's scoping rules are somewhat similar to scheme's.
Lithp was a project for personal enrichment and isn't intended for anything serious. Play with it and it will break. If you fix it you can send me the patches.
