    If you want to use Scala then I would use something like ZIO as it is the closest to an FP application framework.

    > doing FP in Scala versus alternatives

    I think Scala is the language most actual functional programming on this planet takes place these days. Be it just FP or pure FP.

    I especially like pure FP in Scala. One can do that with Cats Effect (from the TypeLevel family of languages) or ZIO. They're both awesome, so check them out and pick what you'll like best.



    You don't even need to reach out to Scala 3 (still not as mature in its tooling support), you can have a great time with the latest Scala 2 (2.13).

    > versus alternatives

    I think of Scala as a opinionated take on ML and a module system that is tailored to JVM (and is seamlessly interoperable with Java) that just happens to have syntax heavy on braces/parentheses. Otherwise, what's not to like? :)

  • A statement about my Scala open source work

    The first point is about a fucking conference in 2016, in which the organizer invited several people with a process (and thoughts) explained here https://degoes.net/articles/lambdaconf-controversy aimed at being blind to sex/religion/political views etc. He repeatedly stated to be in a strong disagreement with "white supremacist" views and the such. The first words of the ZIO's code of conduct are precisely about that btw https://github.com/zio/zio/blob/master/docs/about/code_of_conduct.md, and zio follows the scala code of conduct. You can agree or disagree about whether "allowing that person, selected in the way described above (without any preference at all for white supremacists of course), to speak precisely about one particular topic and only if they adhere to the code of conduct" is "giving them a platform to share their ideas", but even if you do think that the first approach is completely wrong, it's a pretty big jump from here to accuse the person holding that view (actually a less-strong version of it) of being a white supremacist themselves and the same of all people that associate with that person (the organizer) and stalk and harass them for years on end

    Since you are talking about an IO monad, maybe ZIO (https://zio.dev/) offers some interesting ideas. Rather than an IO monad, ZIO is a family of IO monads with type parameters to support user-defined environments and error types.
