And in most C-style languages that don’t have labelled blocks like this, you can use an infinite loop to achieve the same effect; for example, in Rust where labelled blocks aren’t yet stable:

  'label: loop {
      break 'label;
  }

And if you want to go one further on that, you can break with value because Rust is expression-oriented:

  fn main() {
      println!("Hello, {}!", 'label: loop {
          break 'label "world";
      });
  }
