A solution would be to protect the code generated by deriving (Show) from OverloadedStrings and RebindableSyntax extensions.
Yes, I think that's probably the right solution. Ryan, do you agree? Might you do it? I think it's a matter of fiddling with `ib_extensions`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12688#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
