Just wondering what happens if I do this:

boost::shared_ptr<Foo> foo;
boost::shared_ptr<Bar> bar;
if( foo && bar )

 // Do stuff if both pointers are valid...
}

I did not see an overloaded && operator in the interface of the class. When
using normal pointer semantics, this code is valid through implicit
conversion of a pointer value to a boolean type.
 

The same applies to shared_ptr.
