Comparing enums without their associated values

[Nevin]

You could manually create a nested enum without associated values:

enum Foo {
  case bar(Int)
  case baz(String)
  
  var `case`: Case {
    switch self {
    case .bar: return .bar
    case .baz: return .baz
    }
  }
  
  enum Case {
    case bar
    case baz
  }
}
