That's because most (not all, Javascript is a significant
breaker of those rules) C-type languages create a new scope
every time instead of being solely function-scoped no? So
the construct closes over a new name in a different lexical
scope instead of (as in Python, or Javascript) the same name
in the same lexical.

It's not about rebinding so much as about the breadth of
lexical scopes.
