Running Haskell on Guix

Goal: I want to run haskell programs in Guix, I’m using Guix OS/System. There are examples of how to package a haskell development environment using the Guix channels, packages and services, but some are dated and I’m wondering if there’s a better way of doing things now. I want to avoid complicating my home configuration before knowing if there’s a better way to go about things. So far, I can install ghc and run haskell programs without any engineering effort. But I’m missing the haskell-lang...
