How loop variables might be isolated without a nested scope: After a comprehension is parsed, so that names become strings, rename the loop variables to something otherwise illegal.
This doesn't change the situation conceptually, though, since the question arises of why not do the same mangling for names assigned within the comprehension.
A decision still needs to be made about whether we want semantics that leak some things but not others.
