[Sean Seefried]

Hi again,

-----------
d_show = [d| data A = A

              instance Show A  where
                 show _ = "A"
           |]

--------------
gives

----------------------
ghc-6.2: panic! (the `impossible' happened, GHC version 6.2):
         Failed binder lookup: GHCziShow.show {- v rKy -}

Please report it as a compiler bug to glasgow-haskell-bugs at haskell.org,
or http://sourceforge.net/projects/ghc/.
-----------------------
This might not be a bug, but if it's not can you please tell me what I 
am doing wrong?

Sean
