Re: [Boost-users] Macro to contruct/allocate a shared_ptr?

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
