Local function overloading

[Philpax]

While trying to overload a function in local/function scope, I 
ran into this behaviour: http://dpaste.dzfl.pl/b4e8b9ddf78a and I 
was wondering what the cause was.

As far as I can tell, this should be fine in global scope (and it 
is), but I'm curious as to why it doesn't work inside a function.
