a year ago I check carefully what gcc would do by inspecting the
assembler code generated and indeed it does in-place construction. I
since then carelessly always return objects by copy, and when I
convert portion of the code that was returning by ref to return by
copy I usually do not observe any performance slow-down (although I
must say do not always check).
