C++20: Reaching for the Aims of C++
summary
Claims: C++20 delivers concrete, testable advances — import std boosts compile speed ~10× (nine headers gave ~5×, experiments see 0–80×), modules cut transitive header overhead, concepts let templates require a sortable range instead of ad hoc comments, span provides fat-pointer style safety, coroutines and ranges enable generators and pipelines, move semantics and RAII keep resource control zero‑overhead, and the C++ Core Guidelines provide a practical path to modernize large codebases incrementally.
