I'm fine with a better error message.
It would be Much Better if the "note" part only came out if there ''actually was'' a type constructor `(%%)` in scope. And that should be easy to check.
Done, please have a look at D1902. Message example: {{{ Not in scope: ‘-.->’ Note: use ‘type’ keyword to export type constructor ‘-.->’ defined at T11432.hs:9:1 (requires TypeOperators extension) }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11432#comment:28 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
