Side-note: That's certainly something we could add to Batteries, if
needed. Camlp4 is pretty-much necessary to use Batteries anyway and
Camlp4 already defines IFDEF, INCLUDE, etc. We would just need to
complete that DSL perhaps to accept any valid OCaml expression and call
the ocaml interpreter to evaluate these expressions.
