I think this property does apply.  In your example:

It is already known at compile time that the "return x" in g()
refers to an 'x' in the outer scope.  'x' cannot be a local variable
to g() because there are no statements in g() that bind 'x'.

Regardless of whether the binding itself exists yet, you (the reader)
and the compiler can know which scope to look in for the binding at
runtime.  Have i understood your desired property correctly?
