hyphenated-names also makes it much easier to see and remember whether you split something that might be a compound word- did i call it hotDog or hotdog? while hot-dog jumps out as more distinct and harder to mix up with hotdog

plus the canonicalization as ALL-CAPS makes it easy to point out SYMBOLS among the prose of documentation

edit: and people make fun of it for having like six equality functions, but at least it's only got one false value
