| ## The implicit `self` in actors | ||
|
|
||
| Unlike classes where methods must explicitly declare `self` as their first parameter, actors have an implicit `self` that is automatically available. This fundamental difference means that actor methods are defined without a `self` parameter. In fact, using `self` as a parameter name in actor methods or in the actor's initialization arguments will result in an error. | ||
|
|
||
| The implicit `self` in an actor refers to the actor instance itself. This allows an actor to pass a reference to itself to another actor by simply passing `self`. This is particularly useful when implementing callback patterns or when an actor needs to register itself with another actor. |

I don't quite like this wording. It focuses on self is implicit, but self is just not needed to refer to attributes on the own actor.
The sole purpose of self in actor is to get an external view of the actor that we can pass to other actors that need to interact with us. I think we can express this much more concisely.

You are right, the section should focus on what you can not can't do with self :)
