I hope I was able to shed some light both on how pinning is useful, and how we can reason about safety of a typed API in general. Next time, we are going to look at an extension to the pinning API proposed by @cramertj which guarantees that `drop` will be called under some circumstances, and how that is useful for intrusive collections.
