I wish I could.  I'm almost certain that Chris McDonough implemented
one at PyCon 2005 and that Stephan Richter made use of this, but
I can't find it.

I would like to have this.  I can't find a proposal for it, so I
guess we should start with that,  I'll note that I'd like to have an
interface like:

   oidIterator(class_glob='*')

      Returns an iterable of object ids whose dotted class names
      (module_name.class_name) match the given glob.
