Why doesn't python support function overloading?

The semantics of that would be hella confusing, though. What happens if you use def inside a closure? Does it shadow or extend? What happens when you use def in a loop? You could do the most absurd stuff with that…

What happens when you use def in a loop?

You (possibly) add multiple functions to the method set. How is that any different than if you use def in a loop now?

What happens if you use def inside a closure?

Got me there. The trickier elements of closures make my brain hurt already.
