C++20 如何改进了 for 循环语法

🔑 核心要点

• C++ stands out for having to introduce the reference to it’s loop scope with an additional statement.
• What I have demonstrated in this post is precisely the intended use-case for this language feature.
• It may seem very trivial, but small pieces of syntactic sugar like this pay large dividends when used across an entire codebase.
• I’ve only just discovered it myself, but I intend to use it exclusively over the traditional approach going forward.
• It seems to me that the C++ Standards Committee is doing a decent job maintaining the language, and introducing useful features when it makes sense to do so.
