@evan For instance: I can define an application specific behavior for an actor object and build that as an extension. We'll call it Auditing. Now you can follow my note and have a best-effort notification when it is destroyed or otherwise modified. Modifications end up in its inbox/outbox and you can read the history. Very nice
Then the type is [Note & Auditing] and everyone can automatically know by referencing a doc what behavior I attached to it and they know what it means to follow it.
