T.12: Prefer concept names over auto for local variables
T.12:声明局部变量类型时，概念比auto更好
Reason（原因）
auto is the weakest concept. Concept names convey more meaning than just auto.
auto是最弱的概念。相比只用auto，概念名可以传递更多信息。
Example (using TS concepts)
示例（使用TS概念）
代码语言：javascript复制vector<string> v{ "abc", "xyz" };
auto& x = v.front(); // bad
String& s = v.front(); // good (String is a GSL concept)
Enforcement（实施建议）
