Protected nested classes

TypeScript Version: 1.8.9

Code

class Outer {
    protected static Inner = class {}
    private myInner: Outer.Inner;
}

Expected behavior: No errors.

Actual behavior: Compiler error: Cannot find namespace 'Outer'. Line 3, Column 24

Code

class Outer {
    protected static Inner = class {}
    private myInner: Outer.Inner;
}
namespace Outer {}

Expected behavior: No errors.

Actual behavior: Compiler error: Module 'Outer' has no exported member 'Inner'. Line 3, Column 32

Code

export class Outer {
    protected static Inner = class {};
}

export class Child extends Outer {
    static temp = class extends Outer.Inner {}
}

Expected behavior: No errors.

Actual behavior: Compiler error: Property 'Inner' is protected and only accessible within class 'Outer' and its subclasses. Line 6, Column 35

The problem here is that there is no way to define a protected nested class in a way that makes it possible to use in a type declaration. The third example shows why I want to use this: I want a nested class that can only be extended by classes that extend the parent class.

namespace の回避策とサブクラスの拡張ケースを含め、issue にある 3 つの TypeScript の例を再現してください。コンパイラーがネストされたクラス型と protected static メンバーをどのように解決するかを追跡し、有効な例がエラーなしでコンパイルされる一方で、protected メンバーへのアクセスが引き続き強制されることを示す回帰テストのカバレッジを追加してください。
