[Nix-dev] Ghc-mod and the new cabal-1.22

[Carlo Nucera]

Wow, I didn't know it was a possibility, thanks! In that way,
however, I lose the possibility to do `cabal repl` or `cabal build`
because of

> cabal repl
cabal: You need to re-run the 'configure' command. The version of
Cabal being used has changed (was Cabal-1.18.1.5, now Cabal-1.22.0.0).

I tried:
> cabal repl --cabal-lib-version=1.18.1.5
cabal: unrecognized 'repl' option `--cabal-lib-version=1.18.1.5'

Is there a way to fix that, too?

Best regards
Carlo
