Combining C++17 Features
summary
Concrete examples show how if constexpr and the new if with initialization let templates pick different instantiations without SFINAE hacks, how class template argument deduction and a new scope_lock simplify locks, and how fold expressions plus auto non‑type template parameters replace recursive variadic tricks. Measurements report substring creation doubling sort time, switching to string_view cuts that overhead, and combining string_view with parallel algorithms improves throughput; a lifetime‑profile extension flags the remaining view/span hazards at compile time.
