VERSION F:
void LongFunction()
{
    State save = UIElement.GetState();
    register (scopepass) UIElement.SetState(save);
    register (scopefail) UIElement.SetState(Failed(save));
    ...lots of code...
}


VERSION G:
void LongFunction()
{
    State save = UIElement.GetState();
    register (scope) {
        case pass: UIElement.SetState(save); break;
        case fail: UIElement.SetState(Failed(save));
    }
    ...lots of code...
}

VERSION H:
void LongFunction()
{
    State save = UIElement.GetState();
    register {
        case scopepass: UIElement.SetState(save); break;
        case scopefail: UIElement.SetState(Failed(save));
    }
    ...lots of code...
}


P.S.
If I get more ideas I will throw them all (with those already posted) in one
new thread.
