@eborden the placement of recursion schemes is intentional. Did you look at the material it links to? It's not mere recursion, it's the formalization of recursion patterns such as those found in the famous Meijer paper.
So, less "write a foldr" and more "that's a zygo preprohistomorphism!"
The foundational material covers basic recursion already.

Just to be clear, you think we should add ghc, alex and happy to the path, but not cabal?
...and now I understand why. But it might be worth making that explicit.
