----------------------------------------
The Cassandra fellows ran into needing this for their CassandraStorage
implementation. Objections to backporting this into 8.1?

> Pig does not handle deep cast from bag -> bag, tuple -> tuple. Eg, the
> following script does not produce desired result:
> {code}
> a = load '1.txt' as (a0:bag{t:tuple(i0:double)});
> b = foreach a generate (bag{tuple(int)})a0;
> dump b;
> {code}
> The result tuple still contain int inside tuple of bag.
> PIG-613 fix the case we cast bytearray -> bag/tuple, we take complex type
> including inner types, but bag->bag, tuple->tuple is still not effective.
