schemeish

A tiny Scheme interperter based off the metacircular evaluator from SICP. Supports a good amount of the basic primitive and derived expression types, and includes mutable variable and list operations.

To try it out, run cargo run to compile and enter the REPL, or pass in a file path as a command line argument to evaluate.
