And I'm going add it's really weird that your answer ("No, No, Zero") is exactly the same as what the library author said [1] two hours before you posted. But you do that again without acknowledging the author, and with just enough format difference that it's not a copy-paste. It's extremely hard for me to imagine you didn't read what he said before writing that; it's just too similar.
