To clarify, the idea is to declare and kick off all the concurrent tasks upfront (using local variables and the ‘lazy await’ keyword), and then just continue writing the rest of the code ‘as if all the promises are resolved’. The async function automagically pauses whenever needed, so it’s no longer necessary to insert await operators throughout the code.
I admit, this is wishful thinking. I’m just waiting for someone to tell me that it’s not feasible or that it would lead to some very bad code patterns :) On Fri, Feb 24, 2017 at 3:51 AM, Domenic Denicola <[email protected]> wrote: > We already have that feature in the language: it’s called await.
