Syntax support for TOMAP, TOTUPLE, TOBAG
----------------------------------------

Key: PIG-1905
URL: https://issues.apache.org/jira/browse/PIG-1905
Project: Pig
Issue Type: New Feature
Components: impl
Reporter: Daniel Dai


Pig has TOMAP, TOTUPLE, TOBAG UDF. However, it will be much easier if we can add syntax support to it:
{code}
b = foreach a generate [a0#b0] as m;
b = foreach a generate (a0, a1) as t1;
b = foreach a generate {(a0)} as b1; -- b1 is a single tuple bag
{code}

This is a candidate project for Google summer of code 2011. More information about the program can be found at http://wiki.apache.org/pig/GSoc2011
