C.101: Give a container value semantics
C.101:赋予容器值语义
Reason(原因)
Regular objects are simpler to think and reason about than irregular ones. Familiarity.
常规对象相比非常规对象更容易理解和思考。这是亲和度方面的意义。
Note(注意)
If meaningful, make a container Regular (the concept). In particular, ensure that an object compares equal to its copy.
如果可以理解，让容器符合常规(概念)。尤其要保证对象和它的拷贝比较时结果相等。
Example(示例)
void f(const Sorted_vector<string>& v)
{
Sorted_vector<string> v2 {v};
if (v != v2)
cout << "insanity rules!\n";
// ...
}
Enforcement(实施建议)
