Doug Daniels commented on PIG-3136:
-----------------------------------
This would be awesome—-I have wanted it many, many times when I don't care
about the relation name, but just need a processing step to occur. Also, super
helpful for refactoring to add relations in the middle without propagating them
all the way down the chain.
I like the syntax too. It emphasizes continuation from the previous statement
well.
> Introduce a syntax making declared aliases optional

> This is something Daniel and I have talked about before, and now that we have
> the @ syntax, this is easy to implement. The idea is that relation names are
> no longer required, and you can instead use a fat arrow (obviously that can
> be changed) to signify this. The benefit is not having to engage in the
> mental load of having to name everything.
> One other possibility is just making "alias =" optional. I fear that that
> could be a little TOO magical, but I welcome opinions.
