Thanks, Richard.

So adding #yourself is mostly needed for cases where you send #add: to an OrderedCollection (because that returns the added element instead of returning the collection as most expect it would)?

No. It is used when you don't know what the last message send answers. And, *that* is most of the time, because even when you know the answer today, you don't know the future changes.

That is the correct answer. Add it unless you want the result of the last message send.
