#7880: Require "forall" in definitions of polymorphic types ---------------------------------+------------------------------------------ Reporter: monoidal | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.6.3 Keywords: | Os: Unknown/Multiple Architecture: Unknown/Multiple | Failure: GHC accepts invalid program Difficulty: Unknown | Testcase: Blockedby: | Blocking: Related: | ---------------------------------+------------------------------------------ Comment(by monoidal): I believe internally we would change treatment of => everywhere, but the effect would be visible only in type and data declarations, since normal definitions would use implicit quantification as they do it currently. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7880#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
