-     A version of scope that scope an collection of sub store.
-
-     This is kinda a version of `ForEachStoreNode`, not composing `WithViewStore` but creates the sub store.
-
-     ## Example
-     ```
-     struct AppState { var todos: [Todo] }
-     struct AppAction { case todo(index: Int, action: TodoAction }
-
-     store.subscribe(\.todos)
-        .drive(onNext: { todos in
-            self.todoNodes = zip(todos.indices, todos).map { (offset, _) in
-                TodoNode(with: store.scope(
-                    identifier: identifier,
-                    action: Action.todo(index:action:)
-                )
-            }
-        })
-        .disposed(by: disposeBag)
-     ```
-
-     But with example above, you created the entire node again and again and it's not the efficient way.
-     You can do some diffing and only creating spesific index, and rest is handle by diffing.
-
-     - Parameters:
-        - identifier: the identifier from `IdentifierType` make sure index is in bounds of the collection
-        - action: A function to transform `LocalAction` to `Action`. `LocalAction` should have `(CollectionIndex, LocalAction)` signature.
-
-     - Returns: A new store with its domain (state and domain) transformed based on the index you set
