I noticed that this thread became quiet about 25 days ago. There has been a single report in the last 14 days. Until that point, the reports were from people who had used the new syntax for “about a week” or “a few days”.
Coupled with the post about testing needed for async/await, it sounds to me like the feature should bake for a few releases — enough time so that people can really try it out in practice.
“Bake for a few releases” could be made more concrete by finding one or more big projects that currently use await!(), and then wait until they’ve updated their code to use .await. If they don’t see the claimed benefits of chaining .awaits, well then perhaps the syntax isn’t actually doing what people hoped it would do.
