Sorry, I think it is an unreasonable requirement. In my experience with
MTL, I've run into lots of number types that are not comparable with
built-in integers. Using "while (m != IntType())" is much better. Even
better would be for boost to have some sort of number_traits class that
defines one() and zero() functions.

Cheers,
Jeremy
