Anybody still using Python 2.3?

I'm thinking about dropping support for Python 2.3 shortly.  Mainly, 
I'd like to start requiring Python 2.4 in the 0.7 series of 
setuptools, as this will allow me to drop some kludgery.

In general, however, I'd also like to start dropping Python 2.3 
support from other packages, with an emphasis on phasing out the 
quirkier aspects of DecoratorTools usage.  Also, 2.4 has built-in 
sets, threading.local, datetime, unittest-doctest support, etc. etc. 
-- all of which (and more) there are numerous backport kludges for in 
PEAK projects.

Any thoughts?
