Thank you > I would discourage adding just a `.count`. I've heard a few people ask for this over the last year. In almost all cases it is due to people falling back to the way they dealt with enums in Objective C when in fact there is usually a better way in Swift. Adding `.count` would inhibit the discovery of better ways of doing things. However, I'm having a hard time arguing against `.cases`. In at least one place I currently have an `.allCases` computed property on an enum. -- bart
