> * Did an editing pass over the text. Feel free to ignore any you don't like. Thank you a bunch, this is very very helpful! > * I'm a bit late in the process here but I noticed in the diagrams that we use `-` for null. It kinda looks like a minus symbol sometimes instead of indicating a missing element. I wonder if a `_` or `?` might be more clear? I realize part of the issue here is due to limitations of Excalidraw. Not late at all, I can still make changes and I really wish for the diagrams to be as clear as possible. And you are correct, for example in the fixed size list this issue gets very visible when `-7` is used. I am not sure about `?` though, `_` feels a bit better. The specifications use the term `unspecified`. I am not sure what Matt uses in his book as I do not have it with me at the moment, but I think it is some kind of an abbreviation (`U` or `UN` maybe?) > Edit: There was some phrasing that I think could still be tweaked that I didn't add as suggestions so if you'd be okay with that I could do another pass over the text. Lemme know. That would be super great, if you have time, thank you! -- This is an automated message from the Apache Git Service.
