It should read {{{#!hs default encode :: (Generic a, Encode' (Rep a)) => a -> [Bool] }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11417 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

I'd submit the patch myself, but my local copy of the source is outdated and I've forgotten some procedures. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11417#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
