What's the recommended way to handle async object initialization? Since there are no suspend constructor, maybe a fake constructor (suspend operator fun invoke in the companion), or probably just wrap the result into a Deferred<> and call await() every time when needed?

I've been using the fake constructor route without issue, although it is a bit annoying

Instead of invoke, I prefer to make a top level function next to the class with the same name. The IDE seems to suggest this function, but won't suggest the invoke operator function.

just wrap the result into a Deferred<> and call await() every time

Doesn’t look as a good solution for me, it’s constructor after all, it creates all kind limitation when you need multiple instances, and just doesn’t work as constructor

Same as Ben I usually use builder function with the same name as class (and make constructor private) or just builder function with custom name

[gildor]

I would even argue that builder function is better solution in general, even if somehow suspend constructor would be allowed
