I agree with Ralf (and David).  Euphoria is designed to elegantly handle
precisely this situation.  Why would you add totally unnecessary code to a
routine, when the routine already works correctly for all legal values of i
(1 <= i <= length(s))?  To answer Kat's point, s = {} will crash because
there is no legal value possible for i.
