💻 Code

export class Foo {

    protected thisIsProtected = 1;
    private thisIsPrivate = 1;

    bar():Foo {
        const that = this;
        
        return new class extends Foo {

            something() {
                return that.thisIsPrivate + that.thisIsProtected;
            }
        }
    }
}

🙁 Actual behavior

I get a compile error for that.thisIsProtected, but not for that.thisIsPrivate

🙂 Expected behavior

I can access the protected field, like the private
