This would be great. Save us from GROUP ALL/FOREACH, which is awkward.

It would be cool to just treat relations as bags in the general case. They
kind of are, and kind of are not. Causes lots of user confusion.
There are obvious users-doing-dumb-stuff scenarios that arise though.
I guess the Pig philosophy is that the user is the optimizer, though.. so
maybe it's ok.
Would it be possible, and not a ton of work to make the builtin SIZE() work
on a relation? Reason being, I frequently do this:
B = GROUP A ALL;
C = FOREACH B GENERATE SIZE(A) AS total;
DUMP C;
And I would rather do this:
DUMP SIZE(A);
