Async-await hits beta!
Big news! As of this writing, syntactic support for async-await is available in the Rust beta channel! It will be available in the 1.39 release, which is expected to be released on November 7th, 2019. Once async-await hits stable, that will mark the culmination of a multi-year effort to enable efficient and ergonomic asynchronous I/O in Rust. It will not, however, mark the end of the road: there is still more work to do, both in terms of polish (some of the error messages we get today are, um, not great) and in terms of feature set (async fn in traits, anyone?).
