Why don't you put this link in your sig?  It'll save you time.  If I
were you though I would wait a bit until I have had more experience with
Python (In case you change your mind).

In the meantime why not adopt the terminology commonly used on this list
and by Python users at large?  Nobody else would talk about 'a function
that takes a reference to a class'.  It's just plain confusing.
