--- Comment #8 from Collin Funk <collin.funk1 at gmail dot com> --- Thanks for the add. My change was just adding nullptr since it can be used in C code (per C23). I agree with most of the other comments. Probably excessive for -Wall and -Wextra since the idiom exists in old code still. But a warning that is explicitly enabled would be nice.
