While it might be perceived as a limitation there's nothing preventing its addition in a later version if warranted. I believe most/all the various proposals on the PythonDecorators wiki, not just the pie syntax, could be easily adapted to class decoration.

I was going for replacing the module's dict with a dict subclass, and hooking setitem it as an alternative to using settrace to implement this. It's not allowed, though :(. We also need a way to say, "replace the dict into which new definitions are falling" so we can implement decorators inside of class definitions.
