    What breaks if he escapes it? Nothing

      Except it causes confusion for future maintainers. "Why did he escape the question mark? Is that something I haven't learned before? Is this why I'm getting a bug, or should I look somewhere else?"

      Always try to reduce confusion for future maintainers.
