>From http://hackage.haskell.org/trac/ghc/ticket/1953 :
I propose to add a Bounded instance to IntSet.hs.
IntSet is in Ord, and there are only finitely many instances of
IntSet. Therefore there is a min IntSet and a max IntSet. It turns out
these bounds are very simple:
instance Bounded IntSet where
minBound = empty
maxBound = singleton maxBound
Suggested deadline: December 16, 2007.
