I'd prefer to keep a consistent constraint of "iterable of path
entries" for the second value, and allow people to return a non-empty
iterable when they're returning a loader (since it will be ignored
anyway). See my proposed revision to PathFinder.find_module in my
other reply.

I'm definitely *much* happier with the 2-tuple return format over the
introspection based API, though :)

Cheers,
Nick.
