Nope. He's relying on (part of) the interface(s) implemented by the 
first argument. The class object itself has nothing to do with is 
(well... it does, but only as far as it contribute to the implementation 
of the interface expected by the decorator).

I sometimes found staticmethods to be useful, in that they provided 
polymorphic dispatch without having to care about the containing module 
(or whether the object thru which the staticmethod_or_function is 
accessed is a module, class or instance).

+1 on this. So far, the only concrete use case for staticmethod as a 
decorator I can think of is the one exposed above for staticmethods in
