Count me in. I was doing the advent of code and tried to solve one problem with a tree that had parent references. Much thinking was done trying to please the borrow checker with no results, add some inner mutability and I got stucked.

I agree that it should be more prominent in some place. I got most of my info about that in StackOverflow and I tried using a hashmap to simulate the tree structure, but I don't think I finished that one.
