So far, custom completers have been implemented for non-python objects
(where string recognition is enough), but this looks like a good
reason to create an additonal custom completer method for python
objects, using simplegeneric (add complete_object generic to
IPython/generics.py, and on python object completer try calling the

I'll add that when I have the time.
