>       append :: l a -> l a -> l a

New description:

 In section Associated pattern synonyms on
 https://ghc.haskell.org/trac/ghc/wiki/PatternSynonyms
 is written


 {{{
 class ListLike l where
       pattern Nil :: l a
       pattern Cons :: a -> l a -> a
       isNil :: l a -> Bool
       isNil Nil = True
       isNil (Cons _ _) = False

 }}}

 yet should Cons not have signature


 {{{
       pattern Cons :: a -> l a -> l a
 }}}
