Rust really doesn't do ("read the docs and don't screw up").

It's a very much a "bondage and discipline"-style language in the sense that unless you explicitly use "unsafe", you have to prove to the compiler that everything you do is safe. Moving large things is not unsafe because after you move something to a different scope, the original doesn't exist anymore and can't be used, so if you were to accidentally move something and tried to use it again, the compiler would helpfully tell you that the thing you're trying to refer to isn't there anymore.

There is no warning on every time you pass something without copy because passing things to different scopes is extremely common, normal and desired.
