#11540: ghc accepts non-standard type without language extension -------------------------------------+------------------------------------- Reporter: augustss | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.4 (Parser) | Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): That being said, it was decided at some point that we should also allow `foralls` independently from `RankNTypes` with `ExplicitForAlls`. My initial thought was that `RankNTypes` would imply `NestedContexts`, just as it does `ExplicitForAlls`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11540#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
