It's entirely possible to write code that can run on both Python 2 and
Python 3  - at least, if you can target 2.6/2.7 and get the
appropriate future directives. Add in a few exception-guarded imports
for the renamed modules, and then all you're left with is a few things
where you can take a little care while coding, run it through both
versions to test, and have it all work.
