I've just looked at the changes made by 2to3, and it's actually closer than
I had imagined, although I still don't think it's quite close enough to try
to have a single codebase. We could support several of the changes with
little effort, e.g. using print_function from __future__. Unicode strings
would be the big problem: there'd either be conditional code scattered
throughout, or confusing abstractions to hide the difference. We'd also need
to do something with the code that handles old-style classes (I removed
references to ClassType and InstanceType from the py3 branch).
To sum up: I think it's easiest to use the magic of DVCSs and 2to3 to keep

I've done all the changes I've got planned for now (I essentially looked
through the changes I'd had to apply after running 2to3, and reapplied those
that work in 2.6). Is there a standard set of tests I should run to confirm
I haven't broken anything?
