I don't see what's so important about treating the
module namespace differently from other lexically
enclosing scopes for the purpose of resolving names.
Especially only for *assignment* to names.

For read access, we seem to get on just fine without
any keywords to give us a hint what level to look
in. What's different about assignment that we
suddenly feel such a need for them?
