Inspired by your behavior, I looked up the Wikipedia article on Schwartzian transform[1]. The article mentioned that Rust not only provides sort_by_key, but also sort_by_cached_key. :D

I keep saying to colleagues that simply knowing that something exists in a library somewhere is 90% of the skill of modern programming.

I suspect the profession of software archeology form the Vernor Vinge science fiction novels will soon become a reality, especially now that old languages can be uplifted mechanically with AI.
