class AfterLayer implements LayerInterface {

 public function peel($object, Closure $next)
 {
 $response = $next($object);

 $object->runs[] = 'after';

 return $response;
 }

}

$object = new StdClass;
$object->runs = [];

$onion = new Onion;
$end = $onion->layer([
 new AfterLayer(),
 new BeforeLayer(),
 new AfterLayer(),
 new BeforeLayer()
 ])
 ->peel($object, function($object){
 $object->runs[] = 'core';
 return $object;
 });

var_dump($end);
