That seems good, except…

I disagree with this. I believe that PascalCase for pseudo-initializers is more meaningful and modern than “make…”.

Because the compiler can’t yet deal with this…

protocol Monitor {
   typealias Color
   func Color(red: Float, green: Float, blue: Float) -> Color
let color = monitor.Color(red: r, green: g, blue: b)

… I hack around it with this…
func Color_init(red: Float, green: Float, blue: Float) -> Color

…but most of the time, the “_init” is not necessary. Normally we can just namespace out way out of the collision:
protocol Frog {}; extension Frog {
   func String() -> Swift.String {
      return "Frog"
