C++17’s if constexpr replaces complex SFINAE patterns, enabling compile‑time branching that improves readability, safety, and compile times. See a concrete example and practical trade‑offs.
Learn how C++17's constexpr if lets you write cleaner, type‑dependent template code without SFINAE boilerplate, with a concrete example and practical verification steps.
constexpr new/delete behavior The C++20 standard introduced constexpr new and constexpr delete to enable compile‑time dynamic allocation. The specification requires that objects allocated with constexpr new be trivially destructible, but it does not explicitly forbid non‑trivial destructors; instead, it leaves the behavior of constexpr delete ambiguous.
