Hi Abner, I will address Leif's and Mike's comments after stable release.

As we are rushing to get this change to be pulled in stable release 202312 this week, I will just merge this code to master branch and let the discussing keeps going. I think there is no functionality difference base on your suggestions, but it's about the coding practice and readability. Hi Igor, Could you please resend the V6 after stable tag is released if Mike and Leif's comment is reasonable to you?
