[Nix-dev] Overriding Haskell dependencies

Hi Michael,

configuration-common.nix is a function like any other; just "import" it
into your scope.

Yes, I guess so. Even though I'm not quite sure why you'd want to
re-define hackage-packages.nix to begin with. Wouldn't it be easier to
customize the existing package set to your needs rather than re-defining
it from the ground up?

Best regards,
Peter
