Neat, I didn't know nemerle can handle that. Except that when I tried
this, I got a MissingFieldException. See this snippet below.

Am I doing something wrong, or should this be reported as a bug?
Either way, I suppose it should go in Mantis, because even if I'm
doing something wrong, the error message isn't helpful.

/* running this program yields the following error:

Unhandled Exception: System.MissingFieldException: Field
'Nemerle.Builtins.Tuple`2.Field0' not found.

enum Color {
    | Red
};

def _ = match ((Color.Red,Color.Red)) {
    | (Red,Red) => Color.Red
    | _ => Color.Red
}
