C++20’s Coroutines for Beginners
summary
Starts from plain functions and shows C++20 coroutines actually working: implements a generator wrapper type with promise_type, an iterator for range‑based for, a chat-like wrapper that exchanges strings, and a cooperative scheduler using std::list plus awaitable that pushes/resumes handles. Explains customization points like suspend_always/suspend_never and uses co_await/co_yield/co_return; demos compile with clang and GCC and produce the expected interleaved and scheduler output.
