I don't understand the "not shadowing" requirement.  If you're not
going to create a new scope, then

    from foo import *

    if expr as val:
        use(val)

    bar(val)

might very well shadow foo.val and break the invocation of bar.  Is
use of the identifier "val" in this context an error?  Or what?
