Hi guys, quick question, does

async

executed inside a

coroutineScope

finishes before the block exits? (i mean,

coroutineScope

waits

async

, just like it does for

launch

)

Yes.

but only if you start this async using scope of coroutineScope, not some external scope

now I was wondering of a compiler plugin or language feature for:

val foo: Deffered<Int>
corotineScope {
   foo = async { bar() }
}
foo * 2 // foo is smart casted to Int

wait, but why?

the idea was

await

not being needed as

async

was called in the block scope

why it’s not needed? I don’t understand why you think so

but only if you start this async using scope of coroutineScope, not some external scope

becaus eby your comment, at that stage the

async

has finished, so it can actually be smart casted

and as I said, I just don’t see why you need corotineScope or async for this example

Sorry, could have been a better example, image `bar`takes a while, and there are more stuff in the

coroutineScope

block, including other coroutines being launch/async

If you provide such example, we can discuss it, existing example in isolation doesn’t look as something real what should be fixed with a new language feature
