  * Another round of External Core fixes
  
  With this patch, GHC should now be printing External Core in a format
  that a stand-alone program can parse and typecheck. Major bug fixes:
  
  - The printer now handles qualified/unqualified declarations correctly
     (particularly data constructor declarations)
  - It prints newtype declarations with enough information to
    typecheck code that uses the induced coercions (this required a
  syntax change)
  - It expands type synonyms correctly
   
  Documentation and external tool patches will follow.
