The claim is that Rust took espression-orientation from Ruby. That's unlikely - it is much more inspired by FP languages which are also expression oriented.
Ah, you're right, I definitely misread that the first time. I think the only thing that Rust probably was directly inspired by Ruby on was the syntax for closures (which is not exactly the same, but when the closure uses a block rather than returning an expression directly it's similar, and I vaguely recall seeing something about that being intentional).
I don't think anyone claimed that Ruby and Rust were the only two languages with those features, just that they're something they both have in common.
