I'm still not sure how Python 2.8 needs to differ from 2.7. Maybe the
touted upgrade path is simply a Python 2.7 installer plus a few handy
libraries/modules that will now be preinstalled? These modules look
great (I can't say, as I don't have a huge Py2 codebase to judge based
on), and they presumably work on the existing Pythons.
