assigning members of a pair to variables

Is it possible to assign the members of a pair without creating a temporary object?

#include <tuple>
using namespace std;

pair< bool, int > foo()
{
    return make_pair( false, 3 );
}

int main()
{
    int x;
    bool y;

    auto z = foo();
    x = z.second;
    y = z.first;

    return 0;
}

In the above code, the object auto z is needed to "hold" the pair before dissecting it, but its creation might be expensive in the actual code.
