You don&#x27;t need to pay attention to scoped continuations. They&#x27;re a powerful &quot;general&quot; abstraction (like monads), but in practice all you need to know is just the most common kind of continuations -- the (blocking) thread. You&#x27;ll rarely need to use other instances of continuations, as imperative languages already has their function built into the language (exceptions and even mutable variables).
