If Python 2.7 becomes the last of the 2.x series, then I personally  
favor back porting as many features from Python 3 as possible.  I  
still think doing so will help people migrate to Python 3 by getting  
their Python 2 code base as close to Python 3 as possible without  
biting the ultimate bullet.  E.g. for me "from __future__ import  
absolute_import, unicode_literals" in Python 2.6 has helped quite a bit.

I also think Guido's call for feature freeze makes a lot more sense  
when 2.7 is the EOL.  Let's give people migrating to Python 3 a nice  
big stable target to hit.  Improving the stdlib also gives people a  
big carrot to move.

I think it's also necessary to give third party library and  
application authors as much help as possible to provide Python 3  
compatible software.  Putting together Python tools involves so many  
dependencies in a fairly deep stack that even one unconverted library  
can cause everything above it to stall on Python 2.
