I think Martijn raised a good question about the conceptual
interaction of class decorators and inheritance.  (Arguablly the
questions applies to the "advice"-based syntax as well.) If I see:

@some_decorator
class Base:
     ....

class Sub(Base):
     ...

I'm going to wonder how the decorator affects Sub. (Wondering is work. :)

This might be OK for @implements and maybe @adapts, which describe
behavior, but start feeling wonky to me for something like: @utility.
Maybe it's enough to document what the directives do.  Or maybe
something less attached to the class definition would make sense.

I don't know what the right answer is ... at least not yet. :)
