I started writing a different compiler, but tied myself in knots with the type-encoding, and lack of clear plan. I figured I'd step back and try a lisp, because there's a known syntax, and it is minimal.
The end result supports lists, integers, strings, characters, lambdas (with closures), and a reasonable standard library - big enough to hack up a small brainfuck interpreter along with the standard fibonacci, factorial, and fizzbuzz toy programs.
So it's a toy, but it's my toy, and maybe interesting to some!
