This doesn't return the right thing with non const parameters. A very simple result_of compatible wrapper around fusion::at_c will do. In fact I think that fusion should provide function objects for every one of its algorithm.
You mean: std::pair<int, int> pair(1, 2); std::cout << boost::select<1>()(pair) << std::endl; // should output 2 ? I think I'm missing something here... Can you elaborate? -- Dean Michael C.
