Are you sure the assignment to $arrayObject is correct as new DanBettles\Gestalt\A...ion(...) { /* ... */ }) targeting DanBettles\Gestalt\ArrayObject::each() seems to always return null.
                                                                                                                                                                                                        

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
This check looks for function or method calls that always return null and whose
return value is assigned to a variable.


class A
{
    function getObject()
    {
        return null;
    }

}

$a = new A();
$object = $a->getObject();





The method getObject() can return nothing but null, so it makes no sense
to assign that value to a variable.


The reason is most likely that a function or method is imcomplete or has been
