New submission from Daniel Stutzbach <[email protected]>:
>>> isinstance({}.keys(), collections.Set)
True
>>> [method for method in set(dir(collections.Set)) - set(dir({}.keys()))
... if not method.startswith('_')]
['isdisjoint']
(in Python 2.7, use "viewkeys()" instead of "keys")
dict_items has the same problem.
