#5092: Remove Show instance for GHC.Event.IOCallback ---------------------------------+------------------------------------------ Reporter: basvandijk | Owner: Type: feature request | Status: new Priority: normal | Component: libraries/base Version: 7.0.3 | Keywords: Testcase: | Blockedby: Os: Unknown/Multiple | Blocking: Architecture: Unknown/Multiple | Failure: None/Unknown ---------------------------------+------------------------------------------ Conal [http://thread.gmane.org/gmane.comp.lang.haskell.libraries/15592 reported] that the `Show` instance for `IOCallback` conflicts with the more general `instance Show (a -> b)` defined in `Text.Show.Functions`.
The attached patch removes the `Show` instance for `IOCallback` like Bryan propsed. It also removes the `Show` instance for `FdData` since that type contains an `IOCallback`. I don't think this matters because `FdData` is an internal type. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/5092> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler _______________________________________________ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
