This will allow better support of the core common haskell libraries since I do not actually use these packages due to cabal-install. 2. The valid paths that a user can take to install packages are the following: 1. Using cabal-install to install haskell packages. This allows the user to access every haskell package in hackage. The problem is that you are now using packages that are managed outside of pacman. This is usually the best option if you are developing any haskell applications due to the new sandboxing that cabal-install 1.18 has introduced. 2. Using pacman to install haskell packages. This allows the user to have access to a small subset of hackage packages which are known to work on archlinux and are usually good enough for non haskell developers. 3. Using an unofficial repository called Arch Haskell. You could find more information about the repository at the following [page][1] [1]: https://github.com/archhaskell/habs/blob/master/README.md URL: https://www.archlinux.org/news/managing-haskell-packages-with-ghc-782/
