New submission from ThiefMaster:
>>> d = {'1': '2'}
>>> {'1'} < d.keys()
False
>>> {'1'} < set(d.values())
False
>>> {'1'} < d.values()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: unorderable types: set() < dict_values()
Same for e.g. the `-` operator.
Since dict_keys acts like a real set I think dict_values should do so, too. At
least if all the values are hashable.
