More like "this is not a digit at all" vs 42. It evaluates to 0 with a warning, which is the intention--to make sure you check for the zeros before doing arithmetic. But what's an elegant way to see if it's one of the strings without generating the warning? I was thinking of no warning whatever-it-is;, but thought that something direct was available with 5.8.
