DONE: I have written almost 100 posts about C++20. Now, I want to ask you the question: What should be my next big topic? Make your choice in this poll.

In my last post "Starting Jobs with Coroutines", I applied co_await to start a job. In this post, I improve the workflow and automatically resume a job if necessary. In my final step, I resume the job on a separate thread.

C++20 has three new keywords to make a coroutine out of a function: co_return, co_yield, and co_await. co_await requires an Awaitable as arguments and starts the Awaiter workflow. Let me show in this post, what that means.

In my last post in this mini-series to coroutines from the practical perspective, I presented the workflow of "An Infinite Data Stream with Coroutines in C++20". In this post, I use the generic potential of the data stream.

In this post, I analyze the new keyword co_yield. Thanks to co_yield, you can create an infinite data stream in C++20.

This post concludes my posts about co_return in C++20. I started with an eager future, continued with a lazy future. Today, I execute the future in a separate thread using coroutines as an implementation detail.

Based on the coroutines-based implementation of a simple future in my last post "Implementing Simple Futures with Coroutines", I want to go today one big step further. I analyze the workflow of the simple future and make it lazy.

Instead of return, a coroutine uses co_return returning its result. In this post, I want to implement a simple coroutine using co_return.

What happens when you write without synchronization to std::cout? You get a mess. With C++20, this should not be anymore.

Last week, I launched a quiz. The price was it to win one of the five vouchers for my book "C++20".
