 Since `Data.Functor.Classes` is now maintained by the CLC, how about
 instances from [https://hackage.haskell.org/package/prelude-
 extras-0.4.0.1/src/src/Prelude/Extras.hs prelude-extras], at least
 instances for `ZipList`

 {{{#!hs
 instance Eq1   ZipList
 instance Ord1  ZipList
 instance Show1 ZipList
 }}}
