I have the following problem: I would like to define a non-standard prelude that redefines only a few names of the standard prelude. The Haskell report suggests that the following combination should do the job (BUG2A defines the non-standard prelude and BUG2B tries to use it): ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ module BUG2A (module BUG2A, module Prelude) where import Prelude hiding (head) head = "HEAD" ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ module BUG2B where import qualified Prelude import BUG2A ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Unfortunately, loading BUG2B into the Jan2001 beta release gives the following error message: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ERROR BUG2B.hs - Entity "head" imported from module "BUG2A" already defined in module "Prelude" ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
From my understanding of the report, the following BUG2C user module should also do the job, but it gives the same error message:
module BUG2C where
import Prelude ()
import BUG2A
Is this a known problem? Cheers -Peter
