Re: [Haskell-cafe] Re: Import qualified, inverse of hiding
I've dropped it on the discuss page: http://www.haskell.org/haskellwiki/Talk:Import Perhaps others have some input before I stick it on the page.

Exactly! Thanks. Maurício Paulo Tanimoto a écrit : You mean like this? import Data.List (foldl', nub) Or am I misunderstanding your question?

Re: [Haskell-cafe] Re: Import qualified, inverse of hiding
You're welcome. By the way, this page seems pretty comprehensive. http://www.haskell.org/haskellwiki/Import Also, if my memory serves me, Neil Mitchel raised a question about extending the import system not long ago.

Re: [Haskell-cafe] Re: Import qualified, inverse of hiding
Would it make sense to add multiple imports to that wiki page? I'm not sure if this is supported outside of GHC, but I've found it useful. 1 module Main where 2 3 import qualified Prelude as P 4 import Prelude ((++),show,($)) 5 6 main = P.putStrLn (show $ P.length $ show $ [1] ++ [2,3]) On Mon, Sep 15, 2008 at 3:48 PM, Paulo Tanimoto [EMAIL PROTECTED]wrote: You're welcome.
