I think Edward's last post (in January, linked above) addressed those
concerns. In summary: release upstream point releases for hpc and
hoopl that only bump the dependencies of base and time, and provide
instance Applicative IO in the GHC sources for 7.8.5 so that no change
is needed for transformers.
Will that work? Can we go with this?
