struct my_point{
  typedef point_tag tag;
  typedef mpl::int_<2> dimension;
  typedef double coordinate_type;
  typedef cs::cartesian coordinate_system;
  //accessors here, haven't lookup up how those are implemented
};

I do consider this better than the macro, even in this case.
with 3d points, we are up to a macro with 8 arguments.

note that you can still use traits, see my previous email.
