Which brings me to a question: is there a better way to write -inf and +inf in Haskell than "-1/0" and "1/0"?
Why not do it with types:
data InfDbl = Dbl Double | PositiveInfinity | NegativeInfinity
?
Double already has +Inf and -Inf; it's just that Haskell doesn't have
(AFAIK) syntax to write them as constants.
