C++ 에서 가상 템플릿 멤버함수는 지원하지 않나요???

A member template cannot be virtual. For example:

class Shape {
	//...
	template<class T> virtual bool intersect(const T&) const = 0; // error: virtual template
};

This must be illegal. If it were allowed, the traditional virtual function table technique for implementing virtual function could not be used. The linker would have to add a new entry to the virtual table for class Shape each time someone called intersect() with a new argument type.
