Just FYI: lens 4.x is now the default version, and it's used to build all packages except 'diagrams', which still requires lens 3.x. According to <https://github.com/diagrams/diagrams-core/issues/56>, this is about to be remedied, though, and then we can drop lens 3.x altogether.
I hope this helps, Peter _______________________________________________ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev
