I addressed borrowing above. Borrowing is proving lifetime subset properties and that you therefore can avoid increasing the virtual reference count.

And this is not about whether this is useful for beginners. It is to illustrate inherent limitations of the approach.

Right, so what I'm saying is, the description of borrowing doesn't really fit in with the reference counting aspect of the analogy, so it ends up being separate from it.

Right, that was my point. :)

I mean, in the end, do what you'd like. All I'm saying is that I've seen this analogy lead to tons of confusion. YMMV.
