ANNOUNCE: GHC 6.10.1 beta

[Juan Carlos Arevalo Baeza]

   Two regressions with Template Haskell on Windows:

---
{-# LANGUAGE TemplateHaskell #-}
module MkData where

import Language.Haskell.TH
import Language.Haskell.TH.Syntax


op a b = a + b

decl = [d| func = 0 `op` 3 |]
---

   This gives a very weird error:

C:\Users\JCAB\Haskell\THTest>ghc --make main.hs
[1 of 2] Compiling MkData           ( MkData.hs, MkData.o )
attempting to use module `main:MkData' (.\MkData.hs) which is not loaded

   It is related to using inline named function operators `op` in 
declaration quotations in the same module. If the function is defined in 
another module, like `const` then everything works as expected.

   The other:

---
{-# LANGUAGE TemplateHaskell #-}
module MkData where

import Language.Haskell.TH
import Language.Haskell.TH.Syntax


decl name = returnQ $ [ DataD [] (mkName name) [] [RecC (mkName name) 
[]] [] ]
---
{-# LANGUAGE TemplateHaskell #-}
module Main where

import MkData

$(decl "KK")

main = undefined
---

   Also gives a spooky error message:

C:\Users\JCAB\Haskell\THTest>ghc --make main.hs
[1 of 2] Compiling MkData           ( MkData.hs, MkData.o )
[2 of 2] Compiling Main             ( main.hs, main.o )

   I have verified that both were working with GHC 6.8.3. Fail with the 
latest beta 6.10.0.20080925.
