My tutorial and take on C++20 coroutines (2021)

I find the article useful from a "how do C++20 coroutines work" perspective, but these sorts of tutorials don't really help you use coroutines in anything beyond a toy program.

I personally found coroutines are useful only in conjunction with a library wrapping OS system calls to interact with sockets (epoll/iouring on Linux, for instance), providing an event loop, and handles the complexity of multithreading. The most fleshed out one out there is probably boost asio.

>... I sadly found the explanation of coroutines utterly incomprehensible. Same for almost every other explanation I found on the web.

Nice to see a mirror of my experience.

Aren’t there some lightweight wrapper libraries now that make this a bit cleaner?

Nice overview though!

I am not remotely religious, but please pray for us who are still dealing with older versions than that.
