JCF said he manually defunctorized. I'd prefer not to have to butcher my code
to achieve performance, and I'd rather have the compiler do it, if it can.
If ocamldefun can do the work, then I'd rather that there is a compiler switch
to call it transparently rather than have to add more gunk to my makefiles.
Of course, if ocamldefun can do it, modifying one of the existing build
systems to add a defunctorization pass is also an option.

So, are you planning to evolve ocamldefun into a whole program optimizing
OCaml compiler? :-)
