#9242: Implement {-# OVERLAPPABLE #-} and {-# INCOHERENT #-} pragmas -------------------------------------+------------------------------------ Reporter: simonpj | Owner: diatchki Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by tibbe): There's been talk about implementing a `-XNoOrphanInstances` flag, which should make overlapping always safe (I think). If so perhaps it's useful to have a `-XOverlappingInstances` club to allow overlaps everywhere? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9242#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
