Why can't I use 'Type' as the name of an enum embedded in a struct?

Question

The following fails to compile:

struct S1 {
    enum Type {
        case One, Two, Three
    }

    let e1 : Type
    let i : Int
}

func f1(e : S1.Type) {
    S

You can do it like this (as mentioned before, Type is also used within the core of Swift. That's why the compiler is kind of confused). Type used as a name works if the enum is not nested:

enum Type {
        case One, Two, Three
}

struct S1 {

    let e1 : Type
    let i : Int
}

func f1(e : Type) {
   var x = S1(e1: Type.One, i: 1)
}

f1(Type.One)

if you use another name for the enum, you can still nest it:

 struct S2 {


    enum Kind {
        case One, Two, Three
    }

    let e1 : Kind
    let i : Int
}

func f2(e : S2.Kind) {
   var x = S2(e1: S2.Kind.One, i: 1)
}

f2(S2.Kind.One)
