We were looking at a data instance tycon for visibility info, which is the wrong place to look. Look at the data family tycon instead. Also improved the pretty-printing near there to suppress kind arguments when appropriate. }}} -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/11357#comment:7> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
