Maybe I'm old, and curmudgeonly, but it would be nice if the body of
these annoucement emails (not just this one) contained the name of the

part of the third argument to types but that just doesn't feel very Python.
This is all complicated by the fact that I am trying to avoid actually
instancating any of these classes because their purpose is to be passed off
to another framework to be executed. In real life most of the classes would
