Super class members forced to use public for subclass access

[diverted247]

///ERROR - Test.foo is inaccessible

class Test{
    private foo:number = 123;
}
class SubTest extends Test{
    constructor(){
        super();
        this.foo = 456;

    }
}
var subTest = new SubTest();

VS:

///Forced to make Test.foo public to avoid compiler error

class Test{
    foo:number = 123;
}
class SubTest extends Test{
    constructor(){
        super();
        this.foo = 456;

    }
}
var subTest = new SubTest();

The above example will only work is the Test class member foo is made public. The key issue is that it discourages use of the Superclass directly given all member properties and methods must be public.

I think what you want is protected, so #1?
