Thank you!

Please see the answer above to Andrzej. It is indeed similar, although
I am not sure if entirely overlapping. I would say unique_resource
seems like a more specific tool, while unique_val is a low-level
primitive.

I didn't know about the proposal -- but indeed it is interesting to
have an implementation for pre-C++20 users (assuming it will be in
C++20).
