See ARM section 12.1c. "The fundamental rule is that the introduction of
a temporary object and the calls of its constructor/destructor pair may be
eliminated if the only way the user can detect its elimination or
introduction is by observing side effects generated by the constructor
or destructor call."

In your case, all temporaries can be eliminated.
