Well, that's what I saw yesterday but I didn't keep my notes and I can't reproduce it so there was something wrong with my example. I've removed that portion of my answer. But the question is about ${#array[@]}, not ${#array[0]}. Even with your example, if ${#array} and ${#array[@]} were the same you would get 5 5 on line 4, not 3 5 since the expectation is both forms count the elements of the array. In zsh they are equivalent, in bash they are not.
