I had to conditionally expose the `Data.Functor.Identity` module, as otherwise it gets more complicated to tweak GHC's build-system to cope with a `transformers` that would only work with GHC>=7.9 & base>=4.8, as the in-tree `transformers` packages needs to be compiled multiple times, once with the bootstrapping compiler (which is either GHC 7.6 or GHC 7.8 for GHC HEAD), and later-on on with GHC HEAD. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9664#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
