I propose adding NFData instances for all types in base where it makes sense. Attached is a patch which adds instances for most missing types. For many of those types it would be nicer to define the instances in the module where the type is defined, but that would require a circular dependency. Instances in patch: * [http://hackage.haskell.org/packages/archive/base/4.1.0.0/doc/html/Data-Fixed.html Data.Fixed] (E6, E12, Fixed) * [http://hackage.haskell.org/packages/archive/base/4.1.0.0/doc/html/Data-IORef.html Data.IORef] (IORef) * [http://hackage.haskell.org/packages/archive/base/4.1.0.0/doc/html/Data-STRef.html Data.STRef] (STRef) * [http://hackage.haskell.org/packages/archive/base/4.1.0.0/doc/html/Data-Unique.html Data.Unique] (Unique) * [http://hackage.haskell.org/packages/archive/base/4.1.0.0/doc/html/Data-Version.html Data.Version] (Version) * [http://hackage.haskell.org/packages/archive/base/4.1.0.0/doc/html/Foreign-C-Error.html Foreign.C.Error] (Errno) * [http://hackage.haskell.org/packages/archive/base/4.1.0.0/doc/html/Foreign-C-Types.html Foreign.C.Types] (all of them) * [http://hackage.haskell.org/packages/archive/base/4.1.0.0/doc/html/System-Exit.html System.Exit] (!ExitCode) * [http://hackage.haskell.org/packages/archive/base/4.1.0.0/doc/html/System-IO.html System.IO] (IOMode, !SeekMode, !BufferMode) * [http://hackage.haskell.org/packages/archive/base/4.1.0.0/doc/html/System-IO-Error.html System.IO.Error] (IOErrorType) * [http://hackage.haskell.org/packages/archive/base/4.1.0.0/doc/html/System-Mem-StableName.html System.Mem.StableName] (!StableName) For some types I had to resort to tricks like comparing a value with itself to force evaluation since I do not have access to all constructors." proposal closed normal Not GHC libraries (other) 6.10.4 wontfix Unknown/Multiple Unknown/Multiple None/Unknown Unknown
