I recommend dropping the dict.copy() method from Py3.0. * We can already write: newd = copy.copy(d). * We can also write: newd = dict(d) * Both of those approaches also work for most other containers. * The collections.Mapping ABC does not support copy(). * copy() is not a universal feature of mapping like objects * Lists do not have a copy() method. * If we drop dict.copy(), I'll can also drop set.copy() which is unneeded.
Let's make the basic APIs as clean and parallel as possible.
