Sorry, I don't think this looks like Python anymore.  Defining a class
just to get at a throwaway namespace?  Using "@" as an identifier?
Using ":" not as a suite marker?

This doesn't have any way for a casual reader to understand what's
going on.  (Ordinary decorators are bad enough, but I think it is
possible to grasp that the @foo stuff is some kind of "annotation".)
