better do:

  import qualified Data.Map as Map


  import A as B                 x, y, B.x, B.y
  import A as B(x)              x, B.x
  import qualified A as B       B.x, B.y

(cf http://www.haskell.org/onlinereport/modules.html)

i've been hit by this too.
maybe the documentation at beginning of Map.hs should be changed?
