Writing custom C++20 coroutine systems

This detailed technical article explores the complexities of C++20's coroutine system. It provides a comprehensive guide on writing custom coroutine promise classes, managing suspension/resumption with co_await, handling output via co_yield and co_return, and designing non-trivial systems like producer/consumer chains. The author shares insights from personal experience migrating from preprocessor-based coroutines to the new native C++20 support.
