Indeed! That's why I'm still not used to Haskell. While I can do simple things with the language, the abstractions made by the popular libraries written in Haskell require me to understand a certain concept to use them properly. However, while the feature complexity can be avoided at least in the standard libraries, I think that's a more general (possibly cultural) problem, considering a Rust developer will have to use any libraries other than the standard libraries at the end. I believe that's why the Go designers are so wary of adding new features to the language. If there's a feature, library writers will use that feature. Nothing can prevent this.
