That's not how NRVO works. It is only permitted in the case of `return
<local_variable>;`, not `return <local_variable>.<member>;`. It would
be impossible to implement it in the way you're talking about, since
it is the caller who provides storage for the return value. And thus,
the caller would have to know to provide enough storage for `o`.
