// In C++03, we need to resort to tricks or funky
// base classes to control whether classes are copyable:

class Foo : public boost::noncopyable{};

class Bar {
  private:
    Bar(const Bar&); // Not implemented
    Bar& operator=(const Bar&); // Not implemented
};

// In C++11, we don't need these hacks:

class Awesome {
  Awesome(const Awesome&) = delete;
  Awesome& operator=(const Awesome&) = delete;
};
