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).
