In algorithm step 2.4 of 4.2.20.3, oldLenDesc is undefined.  Should this just
say "If A represents a read-only or fixed-length array..." as in 3.3.1?

In algorithm step 3, attempts to set an element with index >= length are
blocked for read-only arrays.  But it still allows indexes < length to set new
values on read-only arrays.
