New description:

 When
 [https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/ghci.html
 #ghci-cmd-:set%20+c collecting type information] (`:set +c`) GHC does not
 collect type information from type variables in type synonyms

 {{{#!hs
 type Endo a = a -> a
 }}}

 data types and families

 {{{#!hs
 data List a = Nil | a ::: List a
 }}}

 fixity declarations

 {{{#!hs
 infixr 5 :::
 }}}

 type class declarations

 {{{#!hs
 class A a where
   getA :: a
 }}}

 and type families.. probably other things: the feature appeared one GHC
 version ago so, has this just not been implemented yet?
