What do you mean by a "real MPL arithmetic types " I'm aware of mpl integral constants, but I don't know other that can be used as arithmetic constants. What a re the requirements for these MPL arithmetic types? Could you elaborate?

MPL arithmetic types should model the MPL Integral Constant concepts as specified here: http://www.boost.org/doc/libs/1_43_0/libs/mpl/doc/refmanual/integral-constan... the idea is just to have your rational type being usable like: boost::mpl::plus::type instead of using ratio_plus etc...
