I wonder how to hide a real property field (not make it private or public but force to use setters and getters) and provide him with simple setter and getter. So I wonder how to create api like:
private:
Property( int my_a);
public:
Property( int my_b);
...
{
set_my_a(1);
cout << get_my_a() << endl;
// my_a = 13; // will cause compiler error
...

You can change a little more if you want:
