  0) they are intrusive! putting code inside a functor may entail the
need to modify also lots of related code. That's one of the worst
thing for a programming feature. Your modification can not be local. I
hate monad for the same reason, and I like ocaml exception mechanism,
and using sometimes global refs for the same reason.
