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(union)
A class method, since you might want to subclass QuerySet (I do).
I found myself needing this a lot, and I think this might be nice for
everyone. If you like the idea, I'll provide the patch.
