#12466: Typechecker regression: Inaccessible code in a type expected by the context -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: Type: bug | Status: new Priority: highest | Milestone: 8.2.1 Component: Compiler (Type | Version: 8.1 checker) | Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: GHC rejects | Unknown/Multiple valid program | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): Oh gosh -- I've clearly been very confused. The original example makes sense to me only with a generic-default signature, so I assumed there was one. I've been thus babbling nonsense. Sorry, all! I have no idea why including the method implementation works. I don't think it should. But I still say the original code should be rejected for the same reasons I've already articulated. If inaccessible code were to become a warning, then the way to fix the warning is not to write the instance. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12466#comment:14 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
