More about coroutines.
C++ coroutines: The mental model for coroutine promises
by Raymond Chen
From the article:
My earlier series on getting started with awaitable objects looked at how you produce awaitable objects, but up until now we haven’t been looking at the other side: How can you be an object that can await other objects?

Creating a task completion source for a C++ coroutine: Failing to produce a result
by Raymond Chen
From the article:
So far, we’ve been working on building a result_holder that can hold any type of result. But what about errors?
Because maybe you have code that’s waiting for a result, and the code that’s supposed to produce the result realizes that it messed up and wants to say, “Sorry, no result today.”...

Cling -- Beyond Just Interpreting C++
by Vassil Vassilev, Wim Lavrijsen, Alexandru Militaru
From the article:
In our previous blog post “Interactive C++ for Data Science” we described eval-style programming, interactive C++ in Notebooks and CUDA. This post will discuss some developed applications of Cling supporting interoperability and extensibility. We aim to demonstrate template instantiation on demand; embedding Cling as a service; and showcase an extension enabling on-the-fly automatic differentiation...

Creating a task completion source for a C++ coroutine: Producing nothing
by Raymond Chen
From the article:
Last time, we created a result_holder that can hold a reference, and we solved it by using a wrapper. But there’s another type that we can’t put in a result_holder, not even with the help of a wrapper. That type is void...

Creating a task completion source for a C++ coroutine: Producing a result with references
by Raymond Chen
From the article:
Last time, we created a result_holder that can be awaited until it is assigned a result, and I noted that the code was broken.
One of the reasons that it’s broken is that it doesn’t handle references properly...

Creating a task completion source for a C++ coroutine: Producing a result
by Raymond Chen
From the article:
We’ve been looking at creating different types of awaitable synchronization objects. This time, we’ll create something analogous to what C# calls a TaskCompletionSource and what PPL calls a task_completion_event. For lack of a better name, I’m going to call it a result_holder...

Ticket Maps
by Anthony Williams
From the article:
It has been an increasingly common scenario that I've encountered where you have some ID that's monotonically increasing, such as a subscription or connection index, or user ID, and you need your C++ program to hold some data that's associated with that ID value. The program can then pass round the ID, and use that ID to access the associated data at a later point...
