I was responding to a comment by Dirk who suggested to use
table.insert to append to the end of an array.
I simply wanted to point out that table.insert(t,v) suffers from the
same problems as t[#t+1]=v

Yes, "first available hole" should be replaced by "first found hole".
It does make a difference.
