Have you actually tried to use Notifications? I imagine something like this:

```ruby
# before
Celluloid.actor_named(self)

# after
Celluloid::Notifications.notifier.publish('celluloid.actor.named', actor)
# or
Celluloid::EventNotifier.publish('celluloid.actor.named', actor)
```

We would have to talk about how to publish, directly through `Celluloid::Notifications.notifier` or through a dedicated notifier like, for example, `Celluloid::EventNotifier` or whatever.
