Comment (by RyanGlScott):

 Then again, it turns out that the `:info` output for `(~~)` is similarly
 broken:

 {{{
 GHCi, version 8.4.3: http://www.haskell.org/ghc/  :? for help
 Loaded GHCi configuration from /home/rgscott/.ghci
 λ> import Data.Type.Equality
 λ> :i (~~)
 class ((a :: k0) ~~ (b :: k1)) => (~~) (a :: k0) (b :: k1)
         -- Defined in ‘GHC.Types’
 }}}
