> This is more readable -
> res = FOREACH gby GENERATE group, FUNC(DISTINCT in.c3);
> than 
> res = FOREACH gby { dist_c3 = DISTINCT in.c3; GENERATE group, FUNC(dist_c3);}
> All relations supported within nested-foreach could be supported for use within expressions.
> other examples -
> res = FOREACH gby GENERATE group, FUNC(limit in.c3 10);
