Ah, I see.

So it seems that the int type almost doesn't need an __int__ method, since
so much power resides in the constructor.

If I subclass int and define __int__ myself, I wonder under what
circumstances __int__ will be invoked -- other than by invoking it
explicitly using myobj.__int__() semantics.
