[Python-ideas] Implement __add__ for set and frozenset

[Imri Goldberg]

+1.

I use union and intersection as sum-like functions from time to time, 
enough to warrant implementation in my "standard utility import".


Although I'm not sure about the interface. A sum-like interface which 
receives a sequence might be better, although they are pretty much 
equivalent.
