These come across as very arbitrary. Why CamelCase rather than capitalize everything? There's no good reason; this is akin to saying there's only one good way to format SQL. Rubbish!
Too bad there isn't a cypherfmt tool (so far as I'm aware). That'd likely bring an end to any debate.
I don't know, I like the to have difference between Cypher commands (all caps) and some other elements.
