rsi - Robert's Scheme Interpreter

This aspirationally titled project is an experimental lisp-like interpreter inspired by Peter Norvig's lis.py but written in Go. Originally this was moving torwards a more Common Lisp-ish implementation, but now it's getting to be closer to scheme as the suggest. It's a learing process, and there is still has a long way to go.

Unlike lis.py, which used native python lists, this implementation is based on cons lists and is aiming to be a more complete implementation. Someday.
