This adds support for container-like types such as Container[T] that don't explicitly specify a view type for T. Instead, a package implementing a container type should also implement and export a ContainerView[T, V] type and a ContainerViewOf(*Container[T]) ContainerView[T, V] function, which returns a view for the specified container, inferring the element view type V from the element type T.
