Note that the [http://hub.darcs.net/ross/transformers/patch/4af2ebe00671e3e20c5ce8edde8027a... upstream version] of `transformers` has already removed these orphan instances.
Oh, didn't notice... however that implies a major version bump for the next `transformer`s package. It'd better if `transformers` kept providing those orphan instances to smooth over the transition for already released package versions... let's hope this doesn't affect too many... :-/ -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10755#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
