带成员函数指针的模板元编程?

退房 this discussion 关于指向作为模板参数的非静态成员的指针。看起来VC++实现有问题。

// Necessary includes
#include <string>
#include <iostream>
#include <ostream>

class Connection{
public:
        // Use std:: for standard string class
        std::string getName() const;
        std::string getAlias() const;
//more stuff
};

typedef std::string (Connection::*Con_Func)() const;

template<Con_Func _Name>
class Foo{
    Connection m_Connect;
public:
    // Constructors don't have return values
    Foo(){
         // Correct syntax for function call through pointer to member
         std::cout << (m_Connect.*_Name)();
    }
};

typedef Foo<&Connection::getName> NamedFoo;
typedef Foo<&Connection::getAlias> AliasFoo;
