syd wonders about a way to return a subset from a large list of
instances of similar classes. A couple different solutions are offered
and the discussion turns to new- versus old-style classes:

Stephen Ferg takes on the twice-yearly task of reminding everyone that
Python is doomed without a CPAN equivalent, meets with the ritual
retorts and everyone eventually moves on, satisfied that we need not

Gabriel Zachmann starts what appears to be the longest thread of the
