Interesting historical note for the Comment.  But I don’t see how that connects with “Example in C.6.8 is wrong”.  The (replacement) Example is required to conform to the standard.  Does the new code have non-conforming parts?  Or is the logic flawed so that the code does not achieve the intended purpose?    Could you be more specific in the Comment on what exactly is wrong with the new code?   If there is an actual defect, we want to get it fixed in this ballot.
