Forcing submodule imports would be the main thing, as at the moment,
you have to choose between repeating the base name multiple times
(once per submodule) or losing the hierarchical namespace.

So where:

    from pkg import mod1, mod2, mod3

bind "mod1", "mod2", and "mod3" in the current namespace, you might
instead write:

    from pkg import .mod1, .mod2, .mod3

to only bind "pkg" locally, but still make sure "pkg.mod1", "pkg.mod2"
and "pkg.mod3" all resolve at import time.

Cheers,
Nick.
