Well, Terry asked. In my corner of the world -- well, iterators are cool. Though a ton of my code broke when we got a 'yield' keyword, as I had used that as a function name all over the place ... But aside from that, pretty much nothing post 1.5.2 really made a difference for us. Some bugs in struct got fixed, and that was nice, but, well on the whole we'd like stone cold dead. >-- >Steven Laura -- https://mail.python.org/mailman/listinfo/python-list
