applications. It is OK with me if ported code only runs on 3.3+, with 
its improved unicode.

If u'' is added, I would like it to be added as deprecated in the doc 
with a note that it is only intended for multi-version Python 2/3 code.

I presume such a hook would simply remove 'u' prefixes and would run 
*much* faster than 2to3. If such a hook is satisfactory for 3.2, why 
would it not be satisfactory for 3.3?
