Hi, I also hope that this is integrated into GHC 7.10.
--Kazu > Hello. > > I'm coming with a proposal for removing transformers dependency > from ghc library. The reason for this proposal that it's not possible > to build consistent environment where a modern libraries (that depend > on a newer transformers or mtl-2.2) and libraries that use ghc API > are used together. And often people are tend to use version that is > bundled with ghc, even if newer are available. > > 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 > and Strict State, and ghc-bin.cabal (ghc/*) uses ones from transformers. > > I have prepared a proof of concept [1], however it doesn't look very clean > and it's quite possible that will require some generalization, for example > introduction of the ghc-transformers-instances package that will have > all required instances. > > Should I continue doing this?
