qualified re-export of Data.Set

[Serge D. Mechveliani]

Dear GHC developers,

Please, how to re-export (qualified) Data.Set, Data.Map ? 

In  ghc-6.2.2,  I used only

  -------------------------------------------
  {-# OPTIONS -fno-warn-duplicate-exports #-}
  module Reexport (module Data.Set, ...)
  ...
  import Data.Set
  -------------------
  module Main
  import Reexport 
  ------------------------------------------


For  ghc-6.4,  I need qualified import of Data.Set, Data.Map 
and need to re-export it. I am trying

---------------------------------------------------------------------
module Reexport (module Set, f, g)
where
import qualified Data.Set as Set

f :: Bool
f = True

g :: Set.Set Bool
g = Set.singleton f
--------------------------
module Main 
import Reexport

main = putStr $ shows v "\n"   where  v = Set.singleton f   -- g 
---------------------------------------------------------------------

Now,  v = g                  works.  
And   v = Set.singleton f  
reports
        Main.hs:3:40: Not in scope: `Set.singleton'

I wonder, how the needed thing can be arranged.

With kind regards,
