> I'm looking for the Swahili and the Japanese of programming. Something completely different, that will expand the ways I'm thinking about programming. I don't really see much benefit in learning Swift or Rust in that regard. I understand what you wrote, but when after 10 years of programming in C++ I've learned Rust, it did actually change the way I think about organizing programs. If you dismiss Rust because it feels "normal", then maybe please revise your position on it. But if you really want Swahili, then try functional programming: Haskell, Racket, etc.
