> But I'm not using nth - probably you misread "neq". No, I'm talking about the code used internally by dolist. If the list over which we iterate were re-computed each time, then to find the "next" element, we'd need to use nth at each iteration. IOW it's a different problem from the re-computation of array bounds at each iteration (which would be inefficient in itself but wouldn't impose additional inefficiencies on the rest of the loop).
