Dmitriy V. Ryaboy resolved PIG-2536.
------------------------------------

    Resolution: Won't Fix

Ok I am convinced by Julien's argument for consistency; don't think the cost/benefit is there to work on this right now, though. Let's leave this as-is; the ticket and patch are here if someone wants to come back later and finish the job.

> Currently, pig does not allow this syntax:
> {code}
> A = load 'thing' (x:int, y:int, z:int);
> B = distinct A.x;
> C = distinct A.(y,z)
> D = distinct C.$0;
> {code}
> and so on. With this patch, it does. I should probably add more tests, though it's a simple patch... it just turns distinct rel.proj into syntactic sugar for distinct (foreach rel generate proj)
