-"""
-There is a way to put keys of any type in a type's dictionary.
-I think this allows various kinds of crashes, but so far I have only
-found a convoluted attack of _PyType_Lookup(), which uses the mro of the
-type without holding a strong reference to it.  Probably works with
-super.__getattribute__() too, which uses the same kind of code.
