Sorry, I've misunderstood.
It seems to me, that Andrei wrote his 'Lying const' statements under the
strong impression, that ZUTO would work as expected. But AFAIR ZUTO never
worked as envisioned and therefor MOJO was developed. But I'm not pushing
you to use a const reference, it was merely a question to understand the
rationale behind this design decision.
