Might be something introduced in Cabal 3.10.x + GHC 9.6. Breaks linting.

Might be a cabal issue, I opened haskell/cabal#9188 , since passing ghc option -fdiagnostics-color=never doesn't do anything to help.

However it would also be nice to set up the terminal as not ANSI color? I presume the default is auto which means it will try to detect.

Hmm, haskell-compile doesn't have this issue

A colleague of mine has the same issue, but on GHC 9.4 (and I think even before that), while us others don't. AFAIK he had it on x86_64 macOS as well as aarch64 macOS. We have other macOS laptops that don't have this problem, using the same tooling (cabal, ghc etc. coming from the same nix development environment).
