You can either
  import Prelude ()

but some things like 'fromInteger' as used for number literals are still
present. You can write the pragma
  {-# OPTIONS -fno-implicit-prelude #-}
 at the top of your module to get completely rid of the Prelude.

You can either do:

import Prelude()

or compile with the -fno-implicit-prelude flag, or add 

{-# LANGUAGE NoImplicitPrelude #-}

to the top of the module.

NoImplicitPrelude is more aggressive than 'import Prelude()'. You will
have to look elsewhere for a better explanation of the difference.

Use:

import Prelude ()

Sorry for the double message, Mauricio. It's the first time I ever
posted to haskell-cafe - figures I'd click on "reply" and not "reply
to all"...

-XNoImplicitPrelude.does this in 6.8.x. In earlier versions (and
apparently in 6.8 too), it's -fno-implicit-prelude.
