> Currently the docs in http://hadoop.apache.org/pig/docs/r0.7.0/piglatin_ref2.html#FOREACH
say that SAMPLE can be used as an operator in nested foreach.  It cannot.
> Also, they do not mention the ability to do projections inside nested foreach, such as
the following:
> {code}
> A = load '/Users/gates/test/data/studenttab10';
> B = group A all;
> C = foreach B {
>     C1 = A.$0;
>     C2 = distinct C1;
>     generate C2;
> }
> dump C;
> {code}
