A good choice to make, the capability to use "from __future__ import 
print_function", or whatever the actual thing is, has been available for 
years.  2to3 has been available for years, six was released at the end 
of June 2010 and there's now future, see http://python-future.org/
Admittedly there's a problem with the porting of code which mixes bytes 
and strings, but that's being addressed right now via PEPs 460, 461 and 
possibly others.
