Hi, is there a way to express hierarchy with expect/actual in Multiplatform? Let's say you have an expected class

ViewContainer

, which is a typealias for

View

on Android-side and

UIView

on iOS-side. And an extension function

ViewContainer.setVisibility(isVisible: Boolean)

. And you also have a second expected class

TextField

, which is a typealias for Android

EditText

/ iOS

UITextField

.

EditText

is a subclass of

TextView

, which is a subclass of

View

.

UITextField

is a subclass of

UIControl

, which is a subclass of

UIView

. So both are related to `View`/`UIView` (

ViewContainer

). It would be nice to tell that the compiler, so that you can invoke the function

setVisibility()

not only on

ViewContainer

, but also on

TextField

or other related classes. Obviously

expect class TextField : ViewContainer

won't work, because it isn't a direct child class. So one way is not having a hierarchy and copy/paste the same extension function with the same implementation to

TextField

and every View type. But shouldn't there be any better solution?
