I call it "aliasing" a module (i.e. aliasing module A's symbols
exported through module B).

Um, sure, but it's can be pretty inconvenient to export 193 symbols
this way :).

I've often thought that it would be nice to have better delegation
support in Python, and no __getattr__() doesn't really hack it.  I'm
encouraged that some of the Py2.2 descr-branch stuff might actually
make this valid programming technique more useful and then even I
could see (eventually) giving up on import-*.
