  4. // into one of those silly top-bar URL shortener things.
  5. //
  6. // Passing `this` and re-aliasing as `window` ensures
  7. // that the window object hasn't been overwritten.

  9. // Example:
  10. //   var window = 'haha, punked!';
  11. //
  12. // Note: Probably unnecessary, but just for kicks.
