i'd suggest something like
shelve.returncopies=0
on a global module level. Every time we are
fixing "python semantics" rather than introducing new
features we should do it on the module level.
These keyword-arguments like 'smart' are code-bloat
and scattered all over the code. Having a section
on top of a python script basically like
assert(pythonversion >2.2.4)
if pythonversion < 2.3.0:
shelve.returncopies=0
somemodule.somefeature=1
is just much nicer and encapsulated.
