#12529: Error message: visible type application of constructor/variable that is not in scope -------------------------------------+------------------------------------- Reporter: Iceland_jack | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: | TypeApplications Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect | Unknown/Multiple warning at compile-time | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): The fact that GHC treats out-of-scope errors as type errors causes degradation of certain error messages, like what you see here. I'm sure there's another ticket tracking this problem, but I'm unable to find it at the moment. Perhaps you can? If I recall, the original error message was about a lack of class instances. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12529#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
