Re: [Python-Dev] why different between staticmethod and classmethod on non-callable object?

It isn't like it is checking explicitly for a function or method, just that it can be called which seems reasonable to me (unless PyCallable_Check() is as off as callable() was).

I think it just checks that there's something in the tp_call slot, which is reasonable -- if it's empty, there's no way that calling the object could ever succeed, so you might as well fail early. -- Greg
