A modern programming language that makes developers happier.

Coming from rx java I was waiting for the `replay` operators to migrate to Flow.
I see the `shareIn()`  but unsure what the scope parameter should be?

shareIn (and other operators which create hot flow) require  scope on which this hot flow will work, because it starts collecting upstream flow and cache values, so to avoid violation of structured concurrence you need some scope to which this flow will be attached

Let’s say if it inside of class with scope, use it, if it’s just top level thing which should be never cancelled, just use GlobalScope (but careful with it)

If GlobalScope is essentially the same what RxJava so no structured concurrence
