Another reason for a separate Hugs.Prelude is that it exports some extra things. This is because Haskell 98 has the Prelude and some other library modules import each other, and Hugs does not support mutually recursive modules, so it simulates it by having the Prelude and the other modules import another module with the real definitions (Hugs.Prelude). Also, Prelude.hs is shared code with GHC, except for the imports (courtesy of cpp). _______________________________________________ Hugs-Users mailing list Hugs-Users@haskell.org http://www.haskell.org/mailman/listinfo/hugs-users
