Isn't that scary? I mean, if I understand it well, a decorated object
supplies extra interfaces, but there's no way to find out by
checking __implements__ or using the introspection tools of the 
interfaces package, right? You just have to 'know' about this, and 
that could be troublesome -- it's why we want interfaces in the first
place.

Or am I missing something?
