Maybe this indicates a problem with __import__.  Twisted has something
called namedAny, and I always use that, because it just works, unlike
__import__, which seems to take too many arguments and has weird behavior
for dotted names.

   me = namedAny(__name__)

The inverse is also available (qual(me) == __name__), and is another
function I've always thought it strange was missing from the stdlib.
