  In 1998 C++, we can solve the problem of how to make a class non-copyable, even to code that is in its class scope. We can create a dummy class which has a private copy constructor that is not implemented: class noncopyable { private: noncopyable(const noncopyable &); }; then simply make this a data member of a class that you don't wish to be copyable: class whatever { private: noncopyable nc; }; The default copy constructor generated by the C++ compiler performs a member-for-member copy, which involves copying nc. That is not possible, so in effect that copy constructor is defeated, not unlike by "= delete". Alternatively use inheritance to mix this in as a trait: class whatever : private noncopyable { // ... };
