Exploring C++17 and beyond
summary
Lists what landed in C++17 and what’s aimed at C++20, claims a clear 2x compile-time win from modules in tested codebases, and gives practical details: use AddressSanitizer (‑fsanitize=address) to find static initialization order fiascos; prefer string_view (pointer+length, constexpr construction) to avoid allocations and gain performance but watch unordered_map lookups and third‑party APIs; sketches operator. proxies that implement pre/postconditions with transactional rollback; shows how if constexpr replaces arcane template branching. Slides and code links are provided.
