Copyable(Copyable&&) = delete;
Copyable& operator= (Copyable&&) = delete;
Unless you are an expert in move semantics (and I mean, really knowledgeable), never delete the special move members. It won't do what you want. If you review someone else's code that has done this, call it out. The explanation has to be really solid, and not "because I don't want the type to move."
Just don't do it.
The proper way to do what you want is to simply declare/define your copy members. The move members will be implicitly inhibited (not deleted, but actually not there). Just write C++98/03.
