mtl (Control.Monad.*) libraries re-export Control.Monad

I just noticed that in the mtl libraries (Control.Monad.*) all re-export Control.Monad and sometimes other modules (Control.Monad.Trans, Control.Monad.Fix). This seems gratuitous, and is especially bothersome when one wishes to hide some export from Control.Monad. Any chance this can be changed? Andrew
