Alan Gates updated PIG-359:
---------------------------
Resolution: Fixed
Status: Resolved (was: Patch Available)
I still don't like the double wrapping. But Shravan is correct that this
matches the previous behavior, and there's no good reason to change it so we
shouldn't. The patch has been checked in.
> Semantics of generate * have changed

> In the main trunk, the script
> A = load 'myfile';
> B = foreach A generate *;
> returns:
> (x, y, z)
> In the types branch, it returns:
> ((x, y, z))
> There is an extra level of tuple in it. In the main branch generate * seems
> to include an implicit flatten.
