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:

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.
