+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. ------------------------- Imri Goldberg www.algorithm.co.il/blogs www.imri.co.il ------------------------- Insert Signature Here ------------------------- Mathias Panzenböck wrote:

As a consequence of Python method implementation, one could write
instead:
A = set.union(S, T, U, V) B = set.intersection(S, T, U, V)

I think this, indeed, reads nicely.
