PyInt_AsLong can already fail with OverflowError - pass it a PyLong object and 
it will try to convert it using the nb_int slot and PyLong_AsLong.

PyInt_AsLong is actually somewhat misnamed - it is really PyNumber_AsLong, 
since it accepts arbitrary objects and coerces them to integers via __int__, 
instead of just accepting PyInt instances.

Cheers,
Nick.
