so, how 'r' can be used uninitialized in this case?

        template <typename R>
        R hex_cast ( const std::string & s )
        {
                if ( s.empty () )
                        throw bad_hex_cast ();
                R r;
                std::istringstream str ( s );
                str >> std::hex >> r;
                return r;
        }
