Content
The patch allows the following syntax for s set/frozenset: * s.union(a, b, c,...) * s.update(a, b, c,...) * s.intersection(a, b, c,...) * s.intersection_update(a, b, c,...) By extension: * set.union(a, b, c,...) # provided a is a set/frozenset * ... Union is extended by iterative application of set_union_internal Intersection is optimized by sorting all sets/frozensets/dicts in increasing order of size and only iterating over elements in the smallest. This was discussed on python-ideas: http://groups.google.com/group/python- ideas/browse_thread/thread/945a6c989ab905a3/54defd5e62b9a2a6
