Okay, I see the intent now too, but I agree with you that I can't see
what advantage asking the object to delete itself provides. Could
someone explain please?

Furthermore, even if there was an advantage to this, why can't the
rack's delete method just be piped through to the object's delete
method? (which I thought was common practice with Specialists)
