Subject: [Caml-list] Warning 28.
Date: Wed, 05 Jun 2013 09:26:03 +0400	[thread overview]
Message-ID: <87sj0xqgb8.fsf@golf.niidar.ru> (raw)


After switching to a newer version of Ocaml I've started to receive
some interesting warnings on my old codebase. And there is one warning
that I do not understand. I have the following patter matching:

    ...
    | Ref n -> ...
    ...

where Ref is:

type t =
  ...
  | Ref of int

Compiler issues me a warning:

«Warning 28: wildcard pattern given as argument to a constant constructor»

Sorry, but if I understand this wording correctly, then I do not see
anything criminal in issuing a wildcard pattern to a constant
constructor. What is wrong?
