Description David Flanagan 2011-06-20 05:09:31 UTC
In algorithm step 2.4 of ยง4.2.20.3, 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.

You're right, thanks.  (I also removed the SameValue checks.)
