I'm wondering if, waiting for some possible feedback from the Committee, we
shouldn't instead simply swap the data members and disregard LWG 675 for now.
Arguably, for std::valarray, where performance is everything, the constant
complexity and total nothrow guarantee that two POD swaps achieve has the
preference to any other nice feature...
