Extending Racket with new languages

Nicely done tutorial on how Racket can be used to write new languages, with a syntax that significantly differs from S-expressions. Apparently, it's super easy.

Most problematic would be handling of 32-bit integers
In Racket, you have the unsafe-fx procedures: limited to fixnums and they overflow. The C standard says nothing on integers being exactly 32 bits, right?

Most problematic would be the parser.
