[Haskell] Hierarchical module namespace extension notsufficiently flexible

[Simon Peyton-Jones]

| If we're going to allow (... items ...) at all, then I suggest instead
that the last example be written:
| 
|    module R( qualified module R(f,g) as Q ) where
|      f = ...; g = ...

Sorry -- that was a typo.  Thanks for spotting it
