I thinks the user space implementation

function array_seek($array, $pos)
{
        $a = array_values($array);
        return $a[$pos];
}

is simple enough to not add a native function for this.

It might not be the most efficient way to do it but I doubt that it is
something done frequently enough to justify another native function.

My 2 cents,
