> we are obligated to then use uncheckedSetIndex for all the elements of the array and the setLength; in fact the debugging checks may obligate us to do this even if the length is zero!

On second though, we can write the debugging checks so they do not obligate us to call setLength. We can set the "did a CreateCompact and needs a setLength" flag only if the initial capacity is non-zero.
