Arrow Fx make monads obscoletes, see the table https://arrow-kt.io/docs/fx/polymorphism/ https://arrow-kt.io/docs/fx/polymorphism/

  The page you linked to describes monads. It sounds like you’re not describing something that makes monads obsolete, but merely a DSL for Kotlin that makes it easier to use monads. Haskell doesn't need that, because monads are already part of the core syntax of the language.

    You clearly didn't read the table that compare the verbosity and cognitive overhead of the Haskell way vs the fx way

      > You clearly didn't read… Just a word of advice—you’re digging yourself in a hole if you make low-quality, ad-hominem comments like that. Comments of the form “you didn’t read X” are specifically discouraged on HN. Maybe you feel good writing it, but nobody feels good reading it and nobody learns anything. I took another look at the page you linked and it still looks like syntactic sugar for Monads. It’s still monads. Monads monads monads. Applicative and Functor are generalizations of Monad.
