FWIW, BCC55 doesn't apply RVO no matter how you write the code.
Still, if there is at least a chance that some future compiler release will
do it, I see no harm in adopting the 'nrvo' idiom you propose.
Probably, I wouldn't 'change' already written code, but I'll take it into
consideration from now on.
