There's class decorators:
@implements(IExample)
class Example:
pass
which could provide the same result in effect, but (as J-P points out)
it's still an API change and so not a direct replacement. IIRC, one of
the arguments for class decorators was that they are a way to avoid
the need for some of this getframe hacking, though.
