I call that "Python 4000", in analogy with Python 3000 which became Python 3, and to further emphasise how far away it is, I've started calling it "Python 5000". As I understand it, Guido has said that we won't be doing a repeat of the 2 to 3 break-a-lot-of-stuff-at-once transition unless there is some unforeseen necessity. > My point is that deprecating a feature is one thing, removing it is > something else. > > We should slow down feature removal, or more generally reduce the > number of backward incompatible changes per release. Have there been many features removed since 3.1? I know there were some features removed in 3.0, like callable(), which were later put back in, but I can't think of anythin removed since then. If there were, the pace of it is pretty slow. > Maybe keep a deprecating warning for 10 years is just fine. > > Extract of the Zen of Python: "Although practicality beats purity." ;-) Aside from things that need to be removed for security reasons, this seems good to me. -- Steve _______________________________________________ Python-Dev mailing list [email protected] https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
