Programmers like to moan that naming things is hard. This may be the case but naming types, functions and variables is a core part of the job.

Such a smart move to use tests not to just test business logic but also to use it to ratchet down code base invariants.

More people have mentioned it and I think it should be part of every Rust tutorial to encourage people to just clone() whenever they get in a jam and get their stuff done: “keep calm, clone and move on”. I think that one thing will make it possible to onboard any team onto Rust quickly and get them shipping.
