 The following code fails a concept check due to a typo in
 boost/geometry/arithmetic.hpp


 {{{
 #include <boost/geometry/geometries/register/point.hpp>
 #include <boost/geometry.hpp>

 struct ConstPoint
 {
     ConstPoint (float x, float y, float z) :
         x (x), y (y), z (z)
     {
     }

     const float x, y, z;
 };

 BOOST_GEOMETRY_REGISTER_POINT_3D_CONST(ConstPoint,
                                        float,
                                        boost::geometry::cs::cartesian,
                                        x, y, z);

 int main (void)
 {
     boost:geometry::model::point <float, 3,
 boost::geometry::cs::cartesian>model;
     ConstPoint cp (1, 2, 3);

     boost::geometry::assign (model, 1, 2, 3);
     boost::geometry::add_point (model, cp);

     return 0;
 }
 }}}

 This fails with a concept assertion:
