Yeah, when this was talked about last time, I wrote PEP 3002 which
requests exactly this:
http://www.python.org/dev/peps/pep-3002/
It basically proposes that all backwards-incompatible changes be
discussed in a PEP somewhere, and that code like Anthony's be added to
2.X to ease the transition. Originally, it has proposed just a
utility like Guido's 2to3 but Guido himself suggested something like
Anthony's approach:
http://mail.python.org/pipermail/python-3000/2006-April/001444.html
I'm planning to update the PEP with any new conclusions arrived at in
this thread.
