My background: I've been subclassing dict since this was possible, to provide not only a count/tally method but also a DIY intern method. Before that I just copied dictmodule.c (every release!) and diffed and hacked about till I had a mydict module. *any* version? Could we make you happy by having a subclass TotallySinfulDict provided as part of the core? You don't have to use it -- come to think of it, you don't have to use a sinful method in the base dict. You could even avert your gaze when reading the documentation. The justification for having it in the core: it's in C, not in Python, it gets implemented and maintained (a) ONCE (b) by folk like the timbot and Raymond instead of having (a) numerous versions lashed up (b) by you and me and a whole bunch of n00bz and b1ffz :-) -- http://mail.python.org/mailman/listinfo/python-list
