You will mostly find PHP Traits here, that add functionality into your objects such as: - Containers: Implements Parent/Child relations between your objects - Hooks: Create hooks and register callbacks with priorities and arguments - Initializers: Automatically execute init() method of your object - Dynamic Methods: Add methods dynamically into existing objects - Factory: Specify class name as a string - App Scope: Inject global "app" object and pass it to new objects Additionally you a much better 'Exception' class for general-purpose exceptions.
