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"
}
}
