 I explained how they enable giving a safe API to code that could previously only be exposed with `unsafe`, and how one could go about proving such a thing.
 This post is about another application of pinned references---another API whose safety relies on the pinning guarantees: Intrusive collections.
 It turns out that pinned references can *almost* be used for this, but not quite.

 Then we `drop` the entry while the collection still exists, and we can see it has vanished from the collection as well.
 
 Notice that using `Pin` in the `insert` method above is crucial: If the collection of the entry were to move around, their respective pointers would get stale!

 Thanks to this guarantee, and unlike in the intrusive-collections crate, `insert` can be called with entries *that do not outlive the collection*.
 With an [API for stack pinning](https://github.com/rust-lang/rfcs/blob/master/text/2349-pin.md#stack-pinning-api-potential-future-extension), we could even have put the `entry` in `main` on the stack.
