Hi,
ticket 1803 implements a set like interface for union/intersection, such as
aQuerySet.union(otherQuerySet)
ticket 1807 implements my original idea under the name list_union,
list_intersection, such as
QuerySet.union(listOfQuerySets)
comments appreciated ;-)

Hi,
what about providing class functions QuerySet.union(cls, qset_list),
QuerySet.intersection(cls, qset_list), both returning cls, such as:
def union(cls, qset_list):
"""Returns the union of a list of QuerySets, a QuerySet."""
return reduce(cls.__or__, qset_list)
union = classmethod(un
