I am not enthusiastic about adding duplication that is useless for
writing Python 3 code, but like others, I do want to encourage more
porting of libraries to run with Python 3. I understand that the unicode
transition seems the be the biggest barrier, especially for some
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.
In case this PEP gets approved I will refactor the tokenize module while
adding support for "u" prefixes and use that as the basis for a
installation hook for older Python 3 versions.
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?
