[Haskell-cafe] odd problem with export list of System.IO

[Manlio Perillo]

Hi.

Maybe I'm missing something, but I don't understand why the following 
program:

module Main where
import System.IO (Handle, withFile, ReadMode)

main = do
   return


fails to compile, with a
Module `System.IO' does not export `ReadMode'



Thanks  Manlio Perillo
