#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 simonpj): Moreover, the current treatment (allowing nested contexts) is inconsistent with GADTs (#12087), which is undesirable. Nothing hard here; just gotta decide what we want and implement it. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11540#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
