When I tried to compile following code with ghc-6.5.20060830,
 {{{
 {-# INLINE (!) #-}
 -- | Returns the element of an immutable array at the specified index.
 (!) :: (IArray a e, Ix i) => a i e -> i -> e
 arr ! i = case bounds arr of (l,u) -> unsafeAt arr (index (l,u) i)
 }}}
 I got error messages below
 {{{
 Data/ArrayBZ/Internals/IArray.hs:109:11: Not in scope: `!'
 Data/ArrayBZ/Internals/IArray.hs:111:0: Not in scope: `!'
 Data/ArrayBZ/Internals/IArray.hs:201:49: Not in scope: `!'
 }}}

 The above code is a part of !ArrayRef library written by Bulat Ziganshin.
