C++20: C++ at 40
summary
Forty-year C++ history leads to concrete C++20 deliverables: modules (import std) reduces rebuilds and targets ~5–10x compile speedups; concepts for generic constraints makes templates readable and errors earlier; ranges and coroutines/generators enable pipeline-style and lazy computation (Eratosthenes example compiles and runs); constexpr and chrono push more logic to compile time and add timezone-aware dates. Advice: adopt modern APIs incrementally, encapsulate or replace legacy modules, use static analyzers and smart pointers to avoid leaks.
