Namely it does not revert the mkPrefixFunRhs refactoring since this is rather independent from the functional changes. Going to try again with a whole working patch }}} -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/13594#comment:15> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
