#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: -------------------------------------+------------------------------------ Comment (by nomeata): Slightly off topic, but maybe `GHC.IO.Handle.Text` can be written so that `castPtr` is not needed. It seems it always works with `Ptr Word8`, but exposes an API that uses `Ptr a` as a generic pointer. The type `a` is never needed inside `GHC.IO.Handle.Text`... -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9163#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
