Wow, ok. So ocamldefun maps ocaml code with functors onto ocaml code without 
functors and, according to their examples, this can result in an 8 times 
performance improvement due to inlining.

This begs the question: why is this functionality not in the compiler? In 
fact, using functors with the current compiler actually reduces 
performance...

Cheers,
Jon.
