I'm getting started with functional programming, which language would you recommend? (gregtech.eu)

Specifically, I'm interested in BEAM, but I'm not sure if I should go for Elixir or Gleam. What seems cool about Gleam is that it has static typing.

I have no experience with functional programming at all btw

When I read about Monads, it looks like to me like generic Rust struct with a generic trait and a (more complex) result as a return value. I have no idea if this is what a Monad basically is or not. For context, I never learned Haskell properly (just tried hello world and read a few topics).

You should think of Monad as basically giving you a way to provide your own implementation of the semicolon operator so that you can dictate what it means to sequence computations of a given type.

I think the mistake I do (and many others) is trying to compare existing mechanisms from other languages, without the full picture around that mechanic. Every time I think to understand what a Monad is, its wrong. :D Guess I have to dive deeper to understand what that actually means, not just as an explanation. Just out of curiosity.
