I'm trying to avoid a huge code bloat for something that should be relatively
simple.  Modifying and using UserDict would give me some 60+ lines of code to do
something I would hope could be done in much less.  A somewhat better option
might be to copy/paste and slightly modify the __init__ and update code from
UserDict which do more or less what I want...  But of course, this has the
problem of any copy/paste solution -- it will inevitably turn into a pain to
sync.  What happens if dict acquires a new keyword argument?  I have to update
my class again...

The code is not hard to write, but it *is* already written for the dict object.
 If there's any way to take advantage of that fact, I'd like to.
