[Python-Dev] nonlocal keyword in 2.x? (original) (raw)

From the Django roadmap for supporting 3.0, using 2.6 as a stepping stone (and if 2.7 was a better stepping stone then it would make it easier):

Is that still a current plan? It's from November 2008.

This gets us to a situation where, about a year after the release of Python 3.0, Django will be ready to make the transition -- the only 2.x Python we'll be supporting is Python 2.6, and 2to3 plus manual effort and available supporting libraries should make it possible to also run Django on Python 3.0 either at that point or not long after.

From there, 2.6 support can be dropped whenever convenient, and Django can move to running only on Python 3.x at whatever time is judged appropriate.

I would claim that this specific plan was ignoring opportunities for migrating to Python 3.0. My Django port demonstrates that you can very well support 2.3 and 3.0 simultaneously:
