Comment (by johnmaddock):

 You're correct of course, in fact rational_adapter is needlessly slow
 because of it's dependence on Boost.Rational which often performs a lot of
 unnecessary copying.

 I really need to rewrite rational_adapter not to use Boost.Rational at

 BTW the front end does have the ability to optimize comparisons when a
 full compare is expensive, but since we can't access the numerator and
 denominator of Boost.Rational without copying, it's unlikely to help so
 much as it should.
