I have no opinion on anything other than that whatever syntax is implemented as long as it allows single underscores between digits, such as 1_000_000 Everything else is irrelevant to me, and if I read code that uses anything else, I'd judge it based on readability and style, and wouldn't care about arguments that "it's allowed by the grammar".
