Just came to my mind:

This version is especially neat because it may be simplified to:
void LongFunction()
{
    State save = UIElement.GetState();
    onscope {
        case success: UIElement.SetState(save); break;
        case failure: UIElement.SetState(Failed(save));
    }
    ...lots of code...
}
