Subject: [Caml-list] Overlapping features of variant types and tuples in Ocaml
Consider the following code:

  type variant =
    | Tuple of (int * int)
    | Non_tuple of int * int

  let contents variant =
    match variant with
      | Tuple x ->
          x
      | Non_tuple x ->
          x

As you can tell, the above code does not compile with Ocaml 3.04:

  The constructor Non_tuple expects 2 argument(s),
  but is here applied to 1 argument(s)

Is there a good reason for this behaviour or would it be purely
beneficial to remove the special handling of type lists in variants?
