定义lambda函数的指针

Question

    function<void()> printer = [&](){
        cout << current->data << " ";
        lastPrinted = current;
        container.pop();
    };

    auto printer = [&](){
        cout << current->data << " ";
        lastPrinted = current;
        container.pop();
    };

以上两种方法均有效。但是下面的代码不起作用：

    void (*printer)() = [&](){
        cout << current->data << " ";
        lastPrinted = current;
        container.pop();
    };

为什么？
