Hi,
I have experienced difficulties using the overlays system together with other 'established' practices.
For instance, given such a 'overlays' definition (https://github.com/CIRB/nixpkgs-config/blob/master/overlays/default.nix#L12) (which works perfectly fine),
this other local nix file (https://github.com/Gabriel439/Haskell-Dhall-Bash-Library/blob/master/release.nix#L3) is going to fail with:
error: attribute ‘dhall-bash’ missing, at /home/vagrant/projects/haskell/Haskell-Dhall-Bash-Library/release.nix:26:18
Somehow it looks like the 'overlays' definition wins in this case, shadowing the local one for haskellPackages ?
As an overlays user, how am I supposed to deal with this ?
Thanks for your help
