 We currently have an unfortunately named `Data.List.OldList`, and no
 terribly clear story to explain it. One concept, due in part to me and in
 part to Carter:

 1. Move all the basics needed to implement `instance Foldable []` from
 `Data.OldList` to `Data.List.Base` (or some similar name).

 2. Move all the "extras" like `inits`, `tails`, and `sort` from
 `Data.OldList` into `Data.List`.

 3. Delete `Data.OldList`.
