Well, why hardcoding that dependency? At most I would see the mpl
versions *in addition* to the ordinary ones. Of course, the former can
be constructed upon the latter by the user

 template <typename T>
 struct mpl_const_min :
        integral_c<T, const_min<T> :: value > {};

and everyone pays only for what he/she uses.

I still don't understand... it must be one of those C++ programmers
eccentricities ;-)
