I recently discovered that my singleton could potentially be used in a way other than as a base class. For example, to create and use a singleton instance of a class which could have other ordinary instances as well, one could just do:

class Example { public: void foo ( ) { } };

// elsewhere...

singleton < Example >::pointer ptr; ptr->foo ( );

I believe (as in "I didn´t tested it" :) that using it in this way would allow multiple instances of Example? For example?

singleton<Example>::pointer ptr; Example other;

This is not a problem. The designer of Example does permit such use: Example a; Example b;
