Oh, you're right - somehow I got convinced that std::tr1::tuple was a flat implementation since it compiles so much faster. But this raises a question - why do the two recursive implementations have such different compile times? Perhaps by analyzing the differences between std::tr1::tuple and std::tuple, we can learn something to our advantage?
