An interpreted lisp, written in Go.

All of the basic lisp features you would expected, and a few extra:

• namespaces (namespace test ...)
• importing files (import core/math)
• for loop construct
• errors and "guards" (think try/except) (guard (error "help"))
• "real" macros
• hashmap values { "a" 1 }
• value expansions (mylist...)
• type hints for functions (defn onlyints (a#int) (println 'a was an int'))
