And 2to3 is a good approach to maintaining a common code base.

Not in the experience of the folks who are actually doing that task:

Well, I personally actually did the task, so that experience certainly isn't universal.

the overhead of running 2to3 every time 'setup.py develop' etc. runs dooms the effort.

How so? Running 2to3 after every change is very fast. I never use setup.py develop, though.

Using 2to3 during ongoing development makes Python feel like Java/C++, where "get a cup of coffee while we rebuild the world" is a frequent occurence.

Unfortunately, these issues never get reported. I worked on porting zope.interface, and it never took 30 minutes for me, not even remotely.

Regards, Martin
