Debian stable and OS X are still major distributions, in my mind.

Yes, I think, many people still use Python 2.3. As for the patch, there's
nothing intrinsic to Python 2.4 that it requires. It simply takes advantage of
Python 2.4 syntax sugar; it does not have to do so.
IMO, widely-used libraries should continue to support Python distributions until
there is a really compelling new feature that cannot be implemented in the old
versions and that we should not drop support for old versions just because they
are old. Most of the "missing features" that I encountered while targeting
Python 2.3 were set(), generator expressions, and decorators. All of them are
very easily worked around in 2.3.
So my question to you is, specifically what features are only in 2.4 that you
think we need to use to support new features in scipy?
