Ok, I confess I haven't been following this thread, and also I don't
know MPL well.  But what's wrong with the above?

   #include <iostream>
   #include "boost/mpl/plus.hpp"
   #include "boost/mpl/int.hpp"
   using namespace boost::mpl;
   using std::cout;
   using std::endl;
   int main() {
      cout << plus< int_<1>, int_<1> >::type::value << endl;
   }

seems to work and prints "2".
