C++ Coroutine Intuition - Roi Barkan - CppNow 2023
Slides: github.com/boostcon
---
As one of the 'big four' new additions to C++20, coroutines allow us to rethink how we design and architect our functions, systems and code.
With no initial support in the STL, many of us are still hesitant to embrace coroutines and consider how to effectively use them to improve the readability, maintainability and composability of our creations.
In this talk, I'll explore and explain topics like stackless, cooperative asyncrony, generators and senders/receivers. Through many concise and different examples of coroutine usage, we'll gain intuition on which types of problems can elegantly be solved with coroutines, and how such solutions can lead to cleaner, safer code.

20:30 the image in slide 13 was taken/borrowed from an awesome talk by Kevlin Henney. czcams.com/video/s2zELGvNlbA/video.htmlh4m12s

[@brynyard]

Very good overview of coroutines, but a lot of the questions underway should've been suspended as the answer was just a couple of slides down the line, and yet others was on a completely different tangent/world/fantasy concept, and as such just big distraction from the otherwise well structured talk.

54:12 Excuse the English - I guess ‘aspirational’ is a better phrasing than ‘inspirational’

[@randall172]

would python's asyncio be a good start pointt for gaining an intuition on coroutines?

[@Roibarkan]

I’m not an expert on python. My brief understanding is that python asyncio is somewhat more high-level than c++ coroutines, and thus python coroutines are probably easier to work with, but potentially less flexible. If one is accustomed to python coroutines- they can be sure that the same model can be done in c++ (and I would look at the asio library and cppcoro as starting points). I do not think that python asyncio supports symmetric transfer, for example, but I’m not sure. Thanks for the question
