final class ExampleEvent
{
}

// Create an Event Listener
final class ExampleEventListener
{
    public function __invoke(ExampleEvent $event): void
    {
        // Handle the event, e.g., print the event class name
        // echo $event::class;
    }
}

// Create a ListenerProvider
$listenerProvider = ListenerProvider::new(); // or new ListenerProvider(Container::getInstance())

// Bind the Listener to the Event
$listenerProvider->listen(ExampleEvent::class, ExampleEventListener::class);

// Create an EventDispatcher
$dispatcher = EventDispatcher::new($listenerProvider); // or new EventDispatcher($listenerProvider)

// Dispatch the Event.
$event = $dispatcher->dispatch(new ExampleEvent());

// Assert the Event is the same as the dispatched Event
assert($event instanceof ExampleEvent);
