That would mean that the length of a function with no arguments is 0,
right? That's bad and will likely introduce subtle bugs because then all
functions with no arguments are suddenly considered false.

What about other callable objects? Classes, methods or instances that
have a __call__ method (They might even implement it through
__getattr__)?
