reversed heapification?

[Jeff Epler]

Can you use something like (untested)
    class ComparisonReverser:
        def __init__(self, s): self.s = s
        def __cmp__(self, o): return cmp(o, self.s)
        def __lt__...  # or whichever operation hashes use
then use (ComparisonReverser(f(x)), i, x) as the decorated item
instead of (f(x), i, x)
