I have been developing in Python since 1.5, and now have to support 2.1 as a minimum version. I do like to keep my code runnable on newer versions however, and am considering the feasability of forward compatibility with Python 3.0.
I also notice the Leo[1] project could use some assistance with forward compatibility.
So I was wondering if anyone else had a need for a 2to23.py tool to help make code compatible with 3.0 but not break it for 2.x.
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... -- Jan Claeys
