Hi, > Any comments/thoughts on this, anyone? I looked at the patch and would like to propose minor modifications. In particular I - removed the 'fix-cc-name phase, which is inherited from ghc-8.8 anyway - converted the failing test (which I can’t get to pass either) into an expected failure instead of nulling it out and - renamed the package to ghc-next, which should avoid https://issues.guix.gnu.org/47335 – if we also rename GHC 8.8 in a different patch. I think we can merge this patch to master, since it only adds a new GHC version and has no further implications. Thoughts? Cheers, Lars
