21:38 <codygman____> I'm having an issue with emacs 27 from nixos-unstable and haskell-mode, error `failed to define function interactive-haskell-mode. See below also for details/minimal repro: https://gist.github.com/codygman/76c2e67d4a55559517e190e6e428f24b

21:39 <codygman____> Oh... is it because I need to use emacsWithPackages?

21:41 <codygman____> follow up question: is there a good way to one-line using emacsWithPackages or will I need to/should I make a nix expression for minimal repros?

21:43 <codygman____> Actually I think maybe for the default emacs stuff I don't need emacsWithPackages since removing `use-package` from my command above throws an error. That means I know it has an effect. So back to the original question.
