Lorand Bendig commented on PIG-3670:
------------------------------------
I think [~aniket486] is right, it shouldn't be allowed to be able to assign an
alias to a STORE, similarly to SPLIT. However, I also think that an aliased
ASSERT makes the interpretation of the pipeline clearer. Then the assigned
alias, which initially didn't have any meaning, could be interpreted in case of
a dump/store as 'foreach A generate * which fails if a0 > 5' .

> PIG-3367 introduce "assert" keyword. However, it can only be used in Java
> embedding, when use registerQuery. In Pig script or Grunt shell, GruntParser
> will complain.
