Just a question:
I wonder about actual usefulness. For a strict safe check you'd also want to 
control method param types and names, not only number. Indeed, param types are 
out of question here, but what about param names? Since you implement that in C, 
is it at all possible to get method param names? (Well, in fact, maybe even 
Python's self-examination power allows that, does it?)
