          Convenience method for retrieval operations. This functions
          identically to :meth:`lookup_in`. As such, the following two
          forms are equivalent:
  
          .. code-block:: python
  
              import couchbase.subdocument as SD
              rv = cb.lookup_in(key,
                                SD.get('email'),
                                SD.get('name'),
                                SD.get('friends.therock')
  
              email, name, friend = rv
  
          .. code-block:: python
  
              rv = cb.retrieve_in(key, 'email', 'name', 'friends.therock')
              email, name, friend = rv
  
          .. seealso:: :meth:`lookup_in`
