Indeed.

One could expand MonadTrans in
instance (MonadTrans t, MonadCGI m, Monad (t m)) => MonadCGI (t m)
replacing it with
instance (MonadCGI m) => MonadCGI (ListT m)
instance (MonadCGI m) => MonadCGI (ContT m)
instance (Error e, MonadCGI m) => MonadCGI (ErrorT e m)
instance (MonadCGI m) => MonadCGI (ReaderT r m)
instance (MonadCGI m) => MonadCGI (StateT s m)
instance (Monoid w, MonadCGI m) => MonadCGI (StateT w m)
instance (Monoid w, MonadCGI m) => MonadCGI (RWST r w s m)
