:) That's working fine. So I recommend you putting
nixpgks-haskell-overlay beneath nixpkgs, then build hack-nix [1], put
ghc in
path, get latest source of poinedList, drop the < 0.5 restriction (it
won't be found by hack-nix). Then run hack-nix --build-env in the directory of
poinedList, source env and start coding

[1]: nix-build hackNix haskell-overlay/default.nix # or such
