It just surprised me that he thought that this committee introduced something new with _Atomic, ... => <stdatomic.h>, ... as _Bool => <stdbool.h> has been in the language since C99. Not only didn't he know that, he thought it was a decision based on what made pretty code or not, he actually thought that they chose to used _Noreturn because they thought it looked pretty, and that they later on added <stdnoreturn.h> because they thought noreturn looked even better, seems to me that he's just oblivious to reserved identifiers.
I don't care who you are or how much code you have written in a language, if you don't know the basics of the language I'm going to say that you don't know it very well.
