I came across this gem recently:

    catch (Exception up)
    {
        throw up;
    }

Truly genius code

  try
     ToastTheGenius;
  except
   On Glass: Exception do
     raise(Glass);
  end;

[ISO-morphism]

Or in Python:

  except Exception as the_roof:
      raise the_roof

I'm... going to have to use this. A lot.
