Expecting one more argument to ‘CPackageIndex ModuleName’

[decentral1se]

I noticed my NeoVim complaining when using neco-ghc and then ran stack exec --no-stack-exe ghc-mod -- debug which gave me the following output:

➜  stack (cabal-parse-fixup) ✗ stack exec --no-stack-exe ghc-mod -- debug

I guess it might be related to the version of Cabal I'm using:

➜  stack (cabal-parse-fixup) ✗  stack exec -- cabal --version
cabal-install version 2.0.0.1

Oh woops, I meant to report this over at ghc-mod, not here - will close!

Ah yes, it's over here - DanielG/ghc-mod#905.
