 - It does work on C extension types, provided they inherit from `Parent`.
 - If I am not mistaken, it is now possible to define a function that does
 some preprocessing on the key. Thus, unhashable arguments should be fine,
 but certainly not out of the box.
 - There is a way to clear the cache. It is a method of the cached method.
 - I think the tests do demonstrate that the cache is working.
