#9163: Ptr should have a phantom role -------------------------------------+------------------------------------ Reporter: simonpj | Owner: Type: bug | 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: #9164 -------------------------------------+------------------------------------ Comment (by simonpj): OK so * I think we have consensus that `Ptr` should have phantom role. Joachim, could you push that through? * Am am not sure what the story is on `FunPtr`. Maybe it doesn't matter for now; but if we leave it as it is, could we add a comment to the role signature saying that it's a conservative choice, and pointing to this ticket? It'd be nice to get this done and closed. Thanks Simon -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9163#comment:16 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
