 - ::Helper::ResultSet correctly uses all Helpers (reported by moltar)
   Note that some deprecated helpers were removed from ::ResultSet, so check
   your code to see if you use the as_virtual_view method.  If you do, replace
   it with as_subselect_rs and you'll be fine.
 - Fix return precedence in test (Reini Urban)
