Subject: empty type (was [Caml-list] Please help a newbie)
   	In Ocaml, the categorical initial also exists,
   thanks to polymorphic variants:
   	type void = [] 
   It is my contention that the type of procedures is wrong
   in ocaml precisely because they return unit, when they
   _should_ be returning void (that is, nothing).
So what typing rules do you use for the empty type? Usually a
type theory is inconsistent as soon as one has an inhabitant of
the empty type.
