So it appears that GHC will warn about "unused" imports when you import qualified if you could have gotten the symbol from somewhere else. For instance, if you write:
import qualified Control.Monad.Trans as Trans import qualified Control.Monad.Writer as Writer
and use "Trans.lift", it will complain because you could have used "Writer.lift".
I think, it's a known issue: http://hackage.haskell.org/trac/ghc/ticket/1148
