I'm not sure if you already have something working, but we have
several in our codebase, all following a similar pattern. For example:
newtype GeoServer a = GeoServer { unGeoServer :: ReaderT
GeoServerState (ServerPartT IO) a }
instance MonadBaseControl IO GeoServer where
newtype StM GeoServer

I have a `newtype Yun a = Yun { unYun :: ReaderT YunEnv (ResourceT IO) a }`
, and i need to define an instance of `MonadBaseControl IO` for it.
Newtype instance deriving don't work here. I guess the answer is simple, i
just can't figure it out, hope anybody can lightening me.
Best regards.
