std::Pin documentation missing example

[bIgBV]

I think the std::Pin documentation is missing an example. Specifically, the Intrusive linked list example. The heading contains references to the example and the the heading Drop guarantee contains the following line:

If your type uses pinning (such as the two examples above),

This leads me to believe that there is a missing example in the documentation.

Was wondering about this too, reading the release notes. Kind of assumed it's "left as an exercise to the reader"

Well, the problem is that implementing the intrusive linked list with a safe API is actually non-trivial. I expect >100 lines. That's why the example is left at the conceptual level.
