I know, I've implemented the feature myself about two months ago. I 
wanted to emphasis on the fact that b'' creates a str object in 2.6 and 
a bytes object in 3.0.

I think it's an reasonable approach to change *all* literals to be 100% 
Python 3.0 compatible. In this particular case I'm for the everything or 
nothing approach.

When the user specifies the py3k_literal mode than 1L and u'' should 
raise a SyntaxError. I'm -0 for no error and -1 for a deprecation 
warning with -3. It'd clutter the parser and tokenizer code even more. 
The warning isn't required, too.
