--- Comment #7 from Andrzej Krzemienski <akrzemi1 at gmail dot com> ---
Just one remark. A warning in this situation is not to just warn about any
deprecated feature, but to indicate something that is very likely to be a bug
(It used to be legal in C++03, so you couldn't legally warn about it; now the
deprecation is just an additional incentive). My guess is that having this copy
constructor implicitly defined when you have a custom destructor is a potential
bug in half of the cases. (Well, "half" is my guess.)
