I'd rather introduce a __parent__ module attribute (in addition to the
existing __name__) so that, for instance, the following would do your job:

from __parent__.__parent__.toto import something

In its spirit, this is similar to the '..' of the file systems.

For top-level modules, __parent__ would be None.

I'm personnally against anything that enlarges the search path uselessly;
because the obvious reason of increased name space collision, increased
run-time overhead etc...
