A Design Space Exploration of Async/Await

Automated excerpt

Many programming languages now provide the async/await keywords for expressing concurrency. The design rationale is pretty consistent: to make concurrent programs look more like straight-line code (see: Python, Rust, or Swift). We therefore describe the paradigm which encompasses async/await as straight-line asynchrony, as opposed to using event loops or callbacks. Language designs for straight-line asynchrony have been brewing for over 15 years.
