Why? Lexical scoping exists for a reason.

It's up to the user anyway. Mandating the workaround may be the easiest to
implement, but it certainly isn't the right thing to do.

Of course, your suggestion might be implemented (*only for local scopes inside
loops, please*) as a temporary fix for type system unsoundness, but don't
assume that this will fix this issue.
