Umm yeah, they've been a part of every ML-family language since the '70s, OCaml, Haskell and Rust included.

I do, but I wasn't aware that Rust was considered in the ML family (ML as Meta Language, like SML/NJ). I'm somewhat skeptical of that.

What I see from Rust is a lot of the really great things from functional languages (esp. strong typing) and beyond, but applying them to a language aiming as low as C. That's certainly interesting.
