I will gladly use it as an implementation strategy "under the hood" if
it makes sense -- I think that with some code analysis (e.g. "what are
the globals here") it could be made to work well.

But I don't think that changing the "from M import v" semantics so
that local assignment to v changes the binding of M.v as well is
defensible.
