在c ++ 11中重新绑定lambda ...是否可能？

#include<iostream>
#include<functional>

int main() {
    int x = 10;
    std::function<int(int)> lambda = [&](int y) { return x + y; };
    x = 20;
    std::cout<< lambda(5)<< std::endl; // 输出 25
    return 0;
}

#include<iostream>
#include<functional>

int add(int x, int y) {
    return x + y;
}

int main() {
    auto bound_add = std::bind(add, std::placeholders::_1, 5);
    std::cout<< bound_add(10)<< std::endl; // 输出 15
    return 0;
}
