Xuefu, can we just follow Alan's suggestion and test to make sure we are not breaking compatibility
on this one.

> In new parser changes, the following statements are treated as same -
> f = foreach l generate a as aa :int;      -- here the column is now called aa and has
type int
> f = foreach l generate a as (aa :int);   -- this should mean that the column has type
"tuple with column aa of type int" 
> With old parser the 2nd statement results in syntax error, which is fine, because it
requires name part . 
> The parenthesis represent tuple in pig.  We should deprecate support for load statement
that takes schema without the parenthesis part , such as following example -
> l = load 'x' as a:int -- It should be as (a :int) , it is treated as such but this is
inconsistent syntax.
