It is. Roll your own interval_traits<>::infinity() if
you want exceptions. We may want to tighten the specs
so that interval_traits::infinity() and ...::nan()
are always called if the arguments produce that result,
so that we are independent on the (implementation-defined)
behaviour of the underlying "double" or whatever.
