用在COM中，類行為比較怪異的代碼

#include <iostream>

using namespace std;

template <typename T>
class Base {
public:
	void fun() {
		cout << "Base::fun" << endl;
	}

	void doSomething() {
		T* pT = static_cast<T*>(this);
		pT->fun();
	}
};

class Drive : public Base<Drive> {
public:
	void fun() {
		cout << "Drive::fun" << endl;
	}
};

class MostDrive : public Drive {
public:
	void fun() {
		cout << "MostDrive::fun" << endl;
	}
};

int main() {
	MostDrive obj;
	obj.doSomething();

	return 0;
}
