Yeah, I don't like that very much. It's like a language where a number is an Object, so it can be null to indicate it wasn't set. But in Vim we have real numbers, so it doesn't fit well. Using -1 for "not set" works better. But then it's different from neovim... -- [clop clop] ARTHUR: Old woman! DENNIS: Man! ARTHUR: Man, sorry. What knight lives in that castle over there?
