Yes it's from the parser generator example

I understand you can do the same in OCaml and F#, they say ML languages are well suited for compiler construction for that. I've been playing with yacc-like Java parser generators and that seems such a time saver compared to a Java class hierarchy.

Edit: you still have to define production rules though, just like in Yacc.
