Hi,

I am trying to do simple pattern matching of these values:
https://github.com/ocaml/ocaml/blob/trunk/parsing/parsetree.mli#L145

What I would like to do is:

   | [Rtag the_whole_4_tuple] ->
       the_whole_4_tuple

However, when I try to do that, I am getting:

  Error: The constructor Rtag expects 4 argument(s),
         but is applied here to 1 argument(s)

This:

    | [Rtag (f1,f2,f3,f4)] ->
        f1,f2,f3,f4

of course works but (regardless of the chosen bound variable names), it looks amateurish.

What's the right way to do this?
(I would like just to bind a 4-tuple and then return it)

(Apologies in advance for a stupid question.)
