Lisp is fun!

I wrote a toy Lisp interpreter this weekend. Programming is pretty much a video game!

(LET ((f (LAMBDA (x) (IF (x (f (CDR x))) recursion!))))
(f (QUOTE (a b c d e))))

→ args: ((a b c d e))
→ args: ((b c d e))
→ args: ((c d e))
→ args: ((d e))
→ args: ((e))
→ args: (nil)
→ recursion!

Outstanding.

I've updated the Unix port and posted it here:

Interestingly, in the C lambda function (on line 297), only the closure block is executed, never the lambda block. The printf on line 321 never happens, only the printf on line 314.
