Unfortunately this doesn't solve the issue I've been seeing since upgrading to GHC 9.4.4 (on both my Hackworth Macbook with Nix, and my personal Linux machine without) where I see hundreds of spurious "overlapping instances" errors, even after clearing ~/.cache/ghcide/ and ~/.cache/hie-bios/.

I'll try to narrow this down and open an upstream bug report, especially since they appear to be on the verge of a release: haskell/haskell-language-server#3599.

Anyway, this PR doesn't make anything worse.

spurious "overlapping instances" errors

Is this another case of the old "package A depends on B which depends on C; if you load a file from A & C but not B, then you get strange errors" issue (I cannot immediately find the upstream bug report for this)?

For example, I get spurious overlapping instance errors from haskell-language-server primer/src/Primer/Core.hs primer/test/Tests/Action.hs, but not from haskell-language-server primer/src/Primer/Core.hs primer/test/Tests/Action.hs primer/gen/Tasty.hs primer/testlib/Primer/Test/TestM.hs

Perhaps the upstream issue haskell/haskell-language-server#3422 is relevant?

I don't think there's any point in merging this, then?

Ah, thanks, yes it is! I was thrown off the scent by the fact this manifests quite differently to in pre-GHC-9.4, and I hadn't been using my load-all-components command from #181 (comment) (see various linked issues from that thread for the upstream discussions) due to haskell/haskell-language-server#3513, and had forgotten about primer/gen.

2.0 is out, hopefully we can build it with haskell.nix as soon as tonight's Hackage bump.
