I ended-up using:
 	PyObject_CallMethod(to->outbasket, "pop", NULL);
The bummer is that this call is effectively used in a loop and runs once
for every data element in an iterable. Something like pop() has such a
tiny granularity that its runtime is overwhelmed by the lookup time to
call it this way. For this reason, I think PyList_Pop() warrants
inclusion in the API much more than low granularity methods like
PyList_Reverse() or PyList_Sort().
