[Python-ideas] import fallback syntax

Hi,

argparse has the same name regardless of its location in site-packages
or the standard library.  For unittest/unittest2, what we do in
distutils2 is to do the import dance in one place and all other modules
import unittest from distutils2.tests.  You can do the same with
lxml.etree/xml.etree.cElementTree/xml.etree.ElementTree.

Can you give examples of projects doing that and their reasons?

One of them is withdrawn; the other one is still open for feedback,
please share your comments on python-dev.
