I've recently been playing with the Rust programming language, and what better way to learn a language than to implement a second language in the language one wishes to learn?! It almost goes without saying that this second language being implemented should be Scheme. Thus, Oxischeme was born.

Why implement Scheme instead of some other language? Scheme is a dialect of LISP and inherits the simple parenthesized list syntax of its LISP-y origins, called s-expressions. Thus, writing a parser for Scheme syntax is rather easy compared to doing the same for most other languages' syntax. Furthermore, Scheme's semantics are also minimal. It is a small language designed for teaching, and writing a metacircular interpreter (ie a Scheme interpreter written in Scheme itself) takes only a few handfuls of lines of code. Finally, Scheme is a beautiful language: its design is rooted in the elegant
