Hi Daniel,

I understand that the Singleto pattern is used to create only one instance of an object.

In the Greenbook\Patterns\Singleton code. I can create two instances of the AnyOldThing class
Code:

AnyOldThing* pp = Singleton<AnyOldThing>::instance();
cout << pp -> coeff() << endl;
AnyOldThing *hp = Singleton<AnyOldThing>::instance();
cout << hp -> coeff() << endl;


Isn't that countering the meaning of the singleton?

Regards
Neville
