Thejas M Nair commented on PIG-3089:
------------------------------------

In my opinion, too many rules for implicit relation names would make pig 
scripts (written by others) hard to read, specially for people who are new to 
pig. I think it is better to just allow name of preceding relation to be 
referred using a special notation.
