As a result of this thread I have created Phab Diff [1]. It contains
required fixes in compiler and ghc-transformers-instance package.
I have tested result on 2 following usecases:
1. I have installed in a sandox transformers-0.3 and ghc-heap-view
that uses them and ghc-lib. (Doesn't require

It sounds to me like Alexander's patch, plus the
solution alluded by Joachim above for invisible packages that don't
clash with ones registered in the ghc-pkg db, would allow us to avoid
having any of the following packages

As transformers usage are quite limited in ghc, and it's really relevant
in ghc-bin, it's possible to duplicate the code, and provide required
fixes in ghc-bin.cabal. As a result ghc uses it's own MonadIO, MonadControl

I thought about providing package ghc-transformers-instances, that will

ghc-tf-instances will depend on current ghc, and current transformers that
could be provided by user environment.

Huge +1 from a Stackage standpoint. The transformers dependency (and other
such dependencies) causes me a huge amount of pain.

Big +1 from me.
doctest is suffering from dependency hell because ghc lib depends on
transformers.

Ok. In this case, I'm interested in main users of ghc library,
as I have to make sure that they will not be broken by
any changes that I'm introduce? I can take few from hackage
but maybe there are ones that users care about. So I can
validate my solution.

Don't worry, we've never given any promise about GHC API
stability across major versions (or minor versions, for that
matter.)
