 The `RecordPuns` extension was accidentally added. In ghc-6.10 it will be
 deprecated and done as an alias for `NamedFieldPuns`.

 See:
 http://hackage.haskell.org/trac/ghc/ticket/2320

 That means people will use `NamedFieldPuns` instead which will then not
 work with older ghc. Cabal should encourage users to switch to
 `NamedFieldPuns` but should translate this into `RecordPuns` when calling
 older ghc versions.
