  // Implementing a loosened valarray return value is tricky.
  // First we need to meet 26.3.1/3: we should not add more than
  // two levels of template nesting. Therefore we resort to template
  // template to "flatten" loosened return value types.
  // At some point we use partial specialization to remove one level

  //       we can't deduce the correct type afterwards.
  //    2) efficiency -- object functions can be easily inlined
  //    3) be Koenig-lookup-friendly
