This is the best I've seen but:

- Why two "pass" blocks?.
- About "exit" would be better before the "body" block and maybe replace 
it with "finally" to save one more keyword.

I'm also assuming that we could also do one liners without the braces:


bool LongFunction()
{
     bool  passed = false;

     scope State save = UIElement.GetState();
     catch UIElement.SetState(Failed(save));
     pass UIElement.SetState(save);
     finally writef('3');
     body {
         ... lots of code ...
     }

     return passed;
  }
