I agree. There's a lot of sibling comments to mine saying "You're thinking of F#" or Ocaml or whatever, and from a purely semantic point I agree with them.

The problem is, where the hell is the enthusiasm for those languages in a similar direction as rust?

The only reason I don't use those languages is because people are overwhelmingly more enthusiastic about rust, which has the majority of features I want. This in turn makes rust have a better developer experience as more people use and contribute to that experience
