>    Affects Versions: types_branch
>            Reporter: Alan Gates

>
> Given a script like:
> {code}
> a = loader 'myfile' as (x, y);
> b = foreach a generate (int)x, (double)y;
> c = group a by x;
> {code}
> you will get an error that x is an unknown alias.  The cast operator is not 
> carrying through the alias.  It should.
