[Haskell-cafe] interval arithmetic for integers?

[Nicolas Frisby]

I did see that one on the wiki; but it doesn't seem to support the
open intervals (i.e. (-inf, 3)) and I'd really like those.

That is the leading candidate right now though...

There was also this one:
  http://www.dinkla.net/fp/cglib.html

It mentions "rangetrees" but I'm not sure if that's the kind I'm
thinking of. That package has what seems like scary math.

Thanks,
Nick
