Review comment:
@xccui OK, I totally agree with you.
In fact, I don't think your review suggestion is unreasonable. I just tried
to explain, what are the reasons for the "ALWAYS" mentioned in your comment. In
addition, I suggest that if the review process is more efficient, it will help
me to adopt your suggestion (because you know that I am not focused on
contributing built-in functions, and most of the time, I need to track a dozen
opened PRs) .
Therefore, I suggest that the next time you feel that there is a problem,
you directly point out what the problem is, that is enough.
