While the Rust version does flow logically, succinctness helps a lot more than people seem to appreciate. It's one of the reasons math notation is often so inconsistent: the brevity allows for easier manipulation and scanning. (Though I would not stretch the analogy too far, as inconsistent and overy brief notation can limit understanding while reading proofs.)

Being able to fit part of a program clearly into 5 lines with fewer characters makes it easier to ensure correctness than an algorithm spread over 10 lines that is full of extra "noise". It's why there's so much syntactic sugar in so many languages.
