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?
