The trouble (shown by Trac #11356) was that we wanted an error message (a kind-mismatch) that involved a type mentioned a (AThing k), which blew up. Since we now seem to have TcTyCons, I decided to use them here. It's still not great, but it's easier to understand and more robust. }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11356#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
