I'm not sure how much effort it's worth devoting to this, but I agree that that the current situation is a mess: * Most things are dealt with as `special_id`; good * 'forall' has its own special lexer treatment, so at least it is not stolen until you switch on `ExplicitForAlls` * But 'role' and 'family' are stolen all the time, in types. Which is a Haskell 98 or 2010 violation. It's annoying! -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10996#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
