It's also (slightly) faster -- the value for $#array is stored in it's
own slot in the AV, which has to be filled in when $#array is
referenced, which it does by (effectively) doing scalar @array, but it's
not stored until it is asked for.
Also, note that
$n <= $#array
and
$i <= @array
are not equivalent: @array == $#array + 1
