interesting idea having default contructor create a default object
Ptr<Test> p1; // default object allocted
Ptr<Test> p2(1, 'a', "hello");
Ptr<Test> p3(Ptr<Text>::Null()); // null object
p1 = Ptr<Text>::Null(); // reset to null
I could even consider an object that can never be null. It would work
like a reference counting reference (instead of reference counting
pointer). it would also be unbreakable. ie no null missuse.
and then as a rule, if more flexibility is needed, then use the
shared_ptr interface instead
