But even better, if we have that syntax sugar the JS engine can automatically throw from the point of the `await` that failed. Think of it exactly like `Task.spawn` or `Promise.spawn` in current promise libs. I need to run for the night. I think we've each made our points though. _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
