Hook Sorting Should Be Done Once

 $any = (new Anemon(self::$lot[1][$c][$id]))->sort([1, 'stack']); 

Whenever a Hook::fire() is invoked, a task to sort the added hooks by stack property is performed. This task can be reduced by only doing the sorting once. But I need an indicator to tell the Hook that it needs to do the sorting:

1. Invoking Hook::set() should trigger the sorting again.
2. Invoking Hook::get() should not trigger the sorting.
3. Invoking Hook::let() should not trigger the sorting as it’s just an action to remove or halt a hook.
4. Invoking Hook::fire() for the first time should trigger the sorting.
5. Invoking Hook::fire() for the second time and the rest should not trigger the sorting, as it’s already done in the first invoke.

 if (count($value = $this->value) <= 1) { 
     if (!$preserve_key) { 
         $this->value = array_values($this->value); 
     } 
     return $this; 
 } 

If the array input contains only 1 item or empty, we can skip the sorting task entirely! 😄
