It would have the semantics that it would remove and return a random /item/ from the dictionary, which the implementation can make the "first" item for convenience purposes. It shouldn't dictate though, that {}.pop() == dict.items().pop() or make any other guarantees about which item gets popped, because other implementations (or indeed, other mapping-conformant objects) may use different underlying representations that could make this inefficient. For added symmetry, {}.pop() should take an optional argument which is the key of the item to remove and return. -Barry
