I have to disagree with that reasoning.  It fails to cover the case 
where f() doesn't actually use its argument arithmetically.   E.g. if

    f(x) = (x > 0) ? (counter = counter + 1) : counter

then f(NaN) yields the current value of "counter".  It doesn't yield 
NaN, so neither should the above "oops" receive such a value.
