I think Gennadiy is including temporaries that can result if you return an expression from a function, i.e., the kind of temporaries that can often be eliminated with move semantics.

Even with lazy functions (or custom operations) there is no temporaries at all.

I'm talking about performing a calculation in the body of a function and then returning the result. Unless a form of the return value optimization applies, you may have a temporary object. Jonathan
