You may derive a class from UserDict to do that, I guess, but
it would seem more natural to me to use plain dicts here, and
a tuple as the index:

    dict={}
    dict['Section','key'] = "some value"

You can do that with a UserDict just as well, of course.  But
is there some reason you really need the multiple-brackets
syntax?  The tuple-based syntax Python offers appears to be
more natural to me.
