Merge Control.Monad.Writer.CPS from writer-cps-mtl #63

Closed taktoa closed 5 years ago

taktoa commented 5 years ago

Currently transformers has a type called Control.Monad.Trans.Writer.CPS.WriterT that does not have accompanying MonadWriter / lifting instances in MTL. These instances are currently implemented as orphan instances in writer-cps-mtl. It should be possible to pretty much just copy over the modules defined in that package over to mtl to gain support.
