Until vendors (other than apple and sun) provide hooks that people can
actually use. Had such hooks been part of _any_ language standard, I
suspect folks with such interests would have merrily coded up systems.

       3. The real problem with interval arithmetic is not that it's
   slow but that on real applications its error estimates are gener-
   ally so pessimistic as to be useless.

At last, something we agree on! But I confess that I have not used it
extensively, so I am prepared to believe that it may have utility I am
not personally cognizant of. Interval techniques will have to be
deployed in large quantities before it can be counted out of the
running, IMHO.
