5931	numeric::interval equal comparison is strange	Per Karlström <perk@…>	Boris Gubenko	"I find that the interval operator== is somewhat strange. Either I have not got exactly how an interval equality operator is supposed to work. Or it is plain wrong. Anyway here is the offending code from boost/numeric/interval/interval.hpp lines 363 to 371

template<class T, class Policies> inline
bool interval<T, Policies>::operator== (const interval_holder& r) const
{
  if (!checking::is_empty(low, up)) {
    if (up == r.low && low == r.up) return true;
    else if (up < r.low || low > r.up) return false;
  }
  throw interval_lib::comparison_error();
}

What surpprises me is how up is compared with r.low and low is comared with r.up"	Bugs	closed	To Be Determined	interval	Boost 1.47.0	Showstopper	invalid
