C RAII での OpenGL オブジェクト ラッパーのコピーと移動の問題を回避するにはどうすればよいですか?

// An OpenGL object wrapper with RAII
class BufferObject {
public:
  BufferObject() { glGenBuffers(1, &buff_); }
  ~BufferObject() { glDeleteBuffers(1, &buff_); }
private:
  GLuint buff_;
};

// Vector of buffer objects
vector<BufferObject> bufVec;
{
  BufferObject some_buffer; // Create buffer object
  // Initialize some_buffer

  // Copy some_buffer into the vector
  bufVec.push_back(some_buffer);
}
// Error: bufVec.back() will reference a deleted object

// Function returning a buffer object
BufferObject InitBuffer() {
  BufferObject buff; // Create buffer object
  // Do stuff with buff

  // Return a copy of buff
  return buff;
}
// Error: The returned buffer will reference a deleted object
auto buff = InitBuffer();

BufferObject(const BufferObject &) = delete;
BufferObject &operator=(const BufferObject &) = delete;

BufferObject(BufferObject &&other) : buff_(other.buff_) { other.buff_ = 0; }
BufferObject &operator=(BufferObject &&other) {
  if (this != &other) {
    Release();
    buff_ = other.buff_;
    other.buff_ = 0;
  }
  return *this;
}
