Then I was right about not mapping "is elem in both sets" to that expression! ;-) But I did make the leap from Serhiy's original expression to "is elem in both sets," which *may* mean that Serhiy's original expression is confusing, but it's probably just further evidence that I'm not actually as sharp as I think I am. > ...
