Py3k-ish:

>>> d = {2: [], 4: {}}
>>> d.items() & d.items()
...
TypeError: list objects are unhashable

Must behave like Python 2.x-ish:

>>> d = {2: [], 4: {}}
>>> set(d.items()) & set(d.items())
...
TypeError: list objects are unhashable

.. right? If so, IIUC, there is nothing to be done about that...
