<?php namespace App;

trait ModelEventHookTrait
{
    protected static function createdHook()
    {
        return function ($model_instance) {
            if (method_exists(__CLASS__, 'createdHandler')) {
                self::createdHandler($model_instance);
            }
        };
    }

    protected static function savedHook()
    {
        return function ($model_instance) {
            if (method_exists(__CLASS__, 'savedHandler')) {
                self::savedHandler($model_instance);
            }
        };
    }

    protected static function withoutEvents(\Closure $callback)
    {
        self::unsetEventDispatcher();
        $callback();
        self::setEventDispatcher(new \Illuminate\Events\Dispatcher);
    }

SampleModel.php

<?php namespace app;

use Illuminate\Database\Eloquent\Model;

class Entity extends Model
{
  use ModelEventHookTrait;
  
  public static function boot()
  {
    parent::boot();

    self::created(self::createdHook());
    self::saved(self::savedHook());
  }
  
  private static function savedHandler($entity)
  {
    $entity->handleEvent();
  }
  
  private static function createdHandler($entity)
  {
    // Callback will run without dispatch registered
    self::withoutEvents(function () use ($entity) {
      $entity->attribute = 10;
      // Will not trigger another Saved Handler Event
      $entity->save();
    });
  }
}

Adds a cleaner default mechanism for adding saved and created handler functions in laravel with a way to control event bubbling
