handcrafted pair_of_ints to guarantee that first and second belong to pair_of_ints proper and not to some implementation-specific base class, which happens with std::pair in MSVC 10 thus precluding the use of boost::multi_index::member as per 14.3.2/5 (no conversions applied to pointer to member functions template arguments).
