[Python-Dev] Another approach for the import mechanism

>     sys.path.extend(newdirs)

I'm not sure how useful that would be (i.e. I haven't done that by
myself), but that could be handled in the proposed mechanism as well. If
/some/dir/web/http/gopher doesn't exist, that mechanism could check if
http.zip exists, or web.zip exists (or __init__.zip inside those
directories). This also has the advantage that you don't have to enforce
a specific format in your code. If you later discover that tar.bz2 has a
better compression, just go for it. OTOH, I understand that this would
lead to extra tests in comparison with your example.
