Dear Caml-list
I have read the following feature of TOM, anti-matching:
http://tom.loria.fr/soft/release-2.4/manual-2.4/manual003.html#toc8
that allow to specify what you don't want to match. For example in a
OCaml like syntax (for the type 'a option = None | Some of 'a):
(function !(Some _) -> assert false)
would raise an exception in case of None. Ok, this is not a really
interesting example but is it a good feature for ocaml ? Is some one
have do a camlp4 extension for this ? I do not find any library for this
in the the ocaml's hump...
Best,
Frédéric Gava
