That's indeed a bit of a nitpick. If you're working with maths, going back to your notes and reading them is really important. If your notes look like Sum(k,math.inf, (math.pipow(sqrt(x),k))...)), it's really not great. So, while you're correct that it's just notation, the issue remains that it's much harder to read maths in ascii.
