  The structure is still interesting.

  The reason the os.path thing actually works is that os is imported
before user code ever gets control -- when site imports os, os can do
what it needs to do.  If it wasn't import before user code is run, it
wouldn't work.  To import a submodule in the general case, the parent
must be a package -- the directory and __init__.py{,c,o} file *must*
  Tedious and somewhat annoying, but that's the current mechanism.

  I don't disagree with your goal of keeping the interface clean --
the fact that it was a module was throwing me off.  When I revised the
documentation to use xml.parsers.expat, I decided not to document it
as a module, but just say it's an object.  (Hmm, now I can think of
another change that's required in the docs regarding this.)
  Sometimes it would be really nice to have an instance that doesn't
have a class for things like this.  ;)
