Semicolons. Statement’s can be written in multiple lines such as rust io::stdin(&mut foo) .unwrap(). Idk if it would work if the newlines were significant. Also when I paste something, it could be ready hard for the formatter to format it.

Not here, because it’s being used as a function argument.

As you can see, rust allows you to not put semicolons at the end of code blocks. The presence of semicolons is not a language killer. It’s a very hard language, but its worth it.
