What exactly are you proposing? We already have 2to3 (http://svn.python.org/view/sandbox/trunk/2to3/) for source-to-source translation from 2.x to 3.0.

Graham wants to convert his code such that it works on both Python 2.x (probably even early versions of it?) & Python 3.x. Not 2 instances of code, but one source that works on both 2.x and 3.x...
