Thanks for the hint.

However, returning an rvalue, even if moved-onto, will generate code for the
destructor. It's not a matter of efficiency, just of code size.

Anyway, I'll do some benchmarks, after I figure out how to work around the
binary compatibility break imposed by having the & in the function that already
existed.
