Recently I realized that a inheriting class is able to call the
super-constructor of its super-class even if it is declared private.
My expectation was that the compiler would force me to call a explicit
super-constructor which is not declared private. Well, it didn't. It compiles
and even linking is no problem.

For illustration of the described problem consider the following example. The different classes are located in different files.

------------------
module abstractClass;

abstract class AbstractClass
{
    private this()
    {
    }
}
---------------------
import abstractClass;

class InheritingClass : AbstractClass
{
    public this()
    {
        super();
    }
}
