private constructors and inheritance

[Dicebot via Digitalmars-d-learn]

http://dlang.org/class.html#constructors

"If no call to constructors via this or super appear in a 
constructor, and the base class has a constructor, a call to 
super() is inserted at the beginning of the constructor."

The fact that call to base constructor is not inserted into 
templated this()() looks like a bug to me.
