Is there still no plans in supporting suspendable properties/delegates (https://youtrack.jetbrains.com/issue/KT-15555) ?

This does not answer your question, but this thread (https://kotlinlang.slack.com/archives/C1CFAFJSK/p1591261760079000) has some good discussion points on the subject
One conclusion from the thread: there's
CoroutineScope.async {}
to produce a
Deferred<T>
that you can
await()
. That is already a quite flexible way to encapsulate an asynchronous result.

It's good if you are just writing plain old code, but not if you are building DSLs. Having to call
await
is clunky. My use case is in spek:
Copy code
val m by memoized { ... }

// it block is a suspending block
it("doSomething") { f.doSomething() }
it("doAnother") { f.doAnother() }
I'm currently working on adding coroutine support in Spek, Each
it
will receive a unique instance of
f
and one improvement I want to do is to allow the two `it`s to be run in parallel. At the moment, the delegate that is backing
f
tracks the instance, I can't really make the two `it`s run in parallel as they share state. What I want to achieve is to store the state in the
coroutineContext
.
that it means the two its can run independently.
