#10577: Use empty cases where appropriate when deriving instances for empty types -------------------------------------+------------------------------------- Reporter: rwbarton | Owner: (none) Type: bug | Status: patch Priority: normal | Milestone: Component: Compiler | Version: 7.11 Resolution: | Keywords: deriving Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #13117, #7401 | Differential Rev(s): Phab:D4047 Wiki Page: | -------------------------------------+------------------------------------- Comment (by mpickering): I still think there should be a "few examples where folks tied knots with fixed points to get inhabitants of Void" seeing as that is the primary motivation for this implementation. They are good for tests and notes even though I accept I will find them dubious. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10577#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
