... which is an alpha of a framework which requires a lot of stuff to
actually be _useful_.  For one thing, we generally discourage
pre-releases.  For another, we discourage multiple versions of
frameworks (ie, no compat-python).

Yes, but the difference can be mitigated by making your code run cleanly
with python 2.6 (... when it's released) and then running a converter.
We'll end up getting python 2.6 in when it comes out, so that'll help
with the first part.  The second part will have to largely be a flag-day
type of event due to the high number of python modules we ship and use
actively.
