I guess I'm wondering if there's a more "common" (or existing) way of doing the following:

sealed class Cargo<T> {
  class Loading<T> : Cargo<T>()
  data class Loaded<T>(val cargo: T) : Cargo<T>()
  data class Error<T>(val cargo: T) : Cargo<T>()
}

loading can be an object there, as you don't need instances

And it can be of type Cargo<Nothing>. 🙂
(then be sure to declare T as covariant: <out T>)
