C++Primer中文版（第五版）：
//运行时错误：迭代器表示要拷贝的范围，不能指向与目的位置相同的容器
slist.insert(slist.begin(),slist.begin(),slist.end());
如果我们传递给insert一对迭代器，它们不能指向添加元素的目标容器。
在新标准下，接受元素个数范围的insert版本返回指向第一个新加入元素的迭代
器。（在旧版本的标准库存中，这些操作返回void。）如果范围为空，不插入任何元素，insert
操作会将第一个参数返回。
例子1：
cpp
int main() {
list<string> sl1 = { "1","2","3" };
_DList<string> sl2 = { "1","2","3" };
vector<string> v = { "quasi", "simba","frollo","scar" };
//将v的最后两个元素添加到list的开始位置
sl1.insert(sl1.begin(), v.end() - 2, v.end());
sl2.std_insert(sl2.begin(), v.end() - 2, v.end());
_pn(sl1);
_pn(sl2);
cout << "----------------------------------------------------------\n";
//添加一列表
sl1.insert(sl1.end(), { "4","5","6","7","中文","8","9" });
sl2.std_insert(sl2.end(), { "4","5","6","7","中文","8","9" });
_pn(sl1);
_pn(sl2);
cout << "----------------------------------------------------------\n";
//复制自己(旧版会运行时错误，迭代器表示要拷贝的范围，不能指向与目的位置相同的容器）
sl1.insert(sl1.begin(), sl1.begin(), sl1.end());
sl2.std_insert(sl2.begin(), sl2.begin(), sl2.end());
_pn(sl1);
_pn(sl2);
}结果：
例子2：
cpp
int main() {
_DList<string> lst1;
list<string> lst2;
string word;
auto iter1 = lst1.begin();
auto iter2 = lst2.begin();
while (cin >> word) {
iter1 = lst1.std_insert(iter1, word); //等价于调用push_front
_pn(lst1);
iter2 = lst2.insert(iter2, word); //等价于调用push_front
_pn(lst2);
}
}结果：
