Rust's influence was OCaml, not Haskell. Its first compiler was written in OCaml. Its syntax directly looks like OCaml and C++ had a baby. It's got ML smells all over it. Haskell is not the sum of Hindley Milner-esque languages.

Personally, never enjoyed Haskell's syntax (or lack of it) and tendency to overthinking. But I did enjoy SML/NJ and OCaml to some extent.
