Note 1: Forwarding functions are specified as a C++14 constexpr since std::forward is not a constexpr within C++11. Note 2: Though I'm not sure why it doesn't compile, some declarations are specified as a C++14 constexpr or non-constexpr. Note 3: Boost.Tuple adaptation and TR1-based tuple implementations are not constexpr.
