In the explanation of
deref coercionand turbofish, the&nodeintroduces an extra level of indirection by taking a reference to&Node<T>. Since Rust's deref coercion can handle this automatically, the closure can be simplified to|node| node, allowing Rust to directly dereference theBoxand return&Node<T>. I’m unsure whether this was added intentionally, but it was a part that confused me while reading.
