In that case, would ReasonML[1] suit you? ReasonML is based on OCaml, just with a more C-like syntax and nicer tooling, etc. OCaml's semantics are very similar in a lot of ways to Rust, perhaps even better in certain ways. Although it's pitched as a compile-to-JS solution for web development, it's perfectly usable as a natively compiled PL too, using `jbuilder` (dune).
