ANNOUNCE: GHC 7.0.1 Release Candidate 2

[Bas van Dijk]

I'm not sure this is in rc2 since I'm using the latest ghc-HEAD (7.1.20101029).

In ghc < 7 you needed to import symbols like fromInteger, (>>=) and
fail when you used them indirectly. For example when using integer
literals or do-notation.

I noticed that in my ghc-HEAD this isn't needed anymore:

{-# OPTIONS_GHC -Wall #-}
{-# LANGUAGE NoImplicitPrelude #-}

import Control.Monad ( return )
import System.IO     ( IO )
import Data.Int

-- Only needed for ghc < 7.
-- In fact, the following gives a redundancy warning in ghc-7:
import Control.Monad ( (>>=), fail )
import Prelude       ( fromInteger )

main :: IO ()
main = do _ <- return (1 :: Int)
          return ()

Is this intentional?
