#8132: Warning for Typeable instances misplaced -------------------------------------------------+------------------------- Reporter: scottgw | Owner: Type: bug | dreixel Priority: normal | Status: new Component: Compiler | Milestone: Resolution: | Version: 7.7 Operating System: Unknown/Multiple | Keywords: Type of failure: Incorrect warning at | Architecture: compile-time | Unknown/Multiple Test Case: | Difficulty: Blocking: | Unknown | Blocked By: | Related Tickets: -------------------------------------------------+------------------------- Comment (by scottgw): That sounds like a reasonable approach: I checked with a (probably insufficient) regex on the latest Hackage archive and there are indeed not many (~90) packages that appear to write an instance by hand for {{{Typeable}}}. Out of curiosity is there guidance on when/how to introduce breaking changes in GHC? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8132#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
