Yeah isn't that my point? Rust isn't trying to be short or elegant. There's no zen of Rust. There are elegant aspects of Rust, but it's not a central goal. Whereas with OCaml it's trying to be elegant. It's encouraging people to write a program where you read it, go "wait, how does that work?", then re-read it and marvel at the beauty of it.
To be clear, elegance is important. A language absent of elegance would be a bore to write (cough Java cough). But too much elegance and it can eclipse the legibility of the language. No type annotations is elegant. Is it legible? Not in my opinion. But perhaps it is in yours.
