#9111: base should export Typeable instances of its promoted data constructors -------------------------------------+------------------------------------ Reporter: goldfire | Owner: 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 ekmett): It would be a lot less brittle than the current situation. Every time I turn around some package I need forgot to write the instance. The safety of Typeable comes from the Typeable requirement at the use site. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9111#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
