The difference is the underlying methods. DictMixin depended on getitem, setitem, delitem, and keys. MutableMapping doesn't need keys but wants __iter__ and __len__. Also, DictMixin did not insist on all of those being present, while MutableMapping won't let you skip any (with delitem being the one most likely omitted). |

Perhaps the best we can do is a warning from the DictMixin constructor in 2.6 when the -3 flag is specified? |

We should hold off on this one for a bit until I can get feedback on whether UserDict, UserString, and UserList should all be in the same place (in the own modules or rolled into collections). |
