Thanks @utdemir , your suggestions were super-useful!

I updated the tutorial to include the usage of [`callCabal2nix`](https://github.com/fghibellini/nix-haskell-monorepo/tree/master/monorepo-nix-expressions) and [shellFor](https://github.com/fghibellini/nix-haskell-monorepo/tree/master/shell.nix).

Only thing that still bothers me about the whole solution is [Custom subscopes for `haskellPackages`](https://discourse.nixos.org/t/custom-subscopes-for-haskellpackages/2998) , hopefully I’ll find a way to fix that soon.
