#10996: family is treated as keyword in types even without TypeFamilies enabled -------------------------------------+------------------------------------- Reporter: oerjan | Owner: Type: bug | Status: new Priority: low | Milestone: Component: Compiler | Version: 7.10.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: GHC rejects | Test Case: type Test valid program | family = family Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by oerjan): I think this would have been so much easier to hack around if there were a way to tell Happy that a rule should resolve all its shift/reduce conflicts by reducing, without assigning precedence to any tokens (which could mess up ''other'' shift/reduce resolutions). Then you'd just declare two tokens `family_kw` and `role_kw`, and two rules {{{ ... family_kw : 'family' %prefer_reduction { ... } ... role_kw : 'role' %prefer_reduction { ... } }}} and use those tokens instead in the keyword-using declarations. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10996#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
