We have a much more extensive directive abstraction though. That should 
make it harder and easier at the same time. :)

Do we really care about "the Python world in general"? Is that relevant 
to the discussion? Can't we just talk about what we care about? The 
Python world in general uses metaclasses for this kind of stuff, which 
relies on base classes too, by the way.

You'll still need a module importing process, as I sketched out 
elsewhere, if you use class decorators, to have the class decorators 
kick in at all for modules you don't need to import otherwise. Note that 
we do support function decorators with Martian.
