Modern Template Techniques
summary
Shows concrete recipes and why they matter: implements an add template using trailing return + decltype and then simplifies with auto; chooses memcpy vs std::copy by detecting std::is_trivially_copyable with enable_if vs constexpr if and tag dispatch for optimal complexity; builds a timing wrapper that uses perfect forwarding (forwarding references + parameter packs and std::forward) to wrap any call, compile-time discards unused branches, and accumulates elapsed time successfully.
