Eli Finkelshteyn commented on PIG-2529:
---------------------------------------

Cool, happy to do it. I don't see a place for tests there though... Should I 
make a src/test/Python dir and throw it in there, or did you have something 
else in mind? This is my first contribution, so I'm a little fuzzy on what's 
expected behavior.

> As per a conversation on the Pig user list, I think it makes sense to create

> and quick I wrote to convert a bag of single item tuples to one single tuple:
> @outputSchema("t:tuple()")

> def bagToTuple(bag):                                                          
>                  
>   t = tuple([item[0] for item in bag])                                        
>          
>   return t
