smart pointers + “this” considered harmful?

Question

In a C++ project that uses smart pointers, such as boost::shared_ptr, what is a good design philosophy regarding use of \"this\"?<

Answer 1

Another reason to pass around this is if you want to keep a central registry of all of the objects. In the constructor, an object calls a static method of the registry with this. Its useful for various publish/subscribe mechanisms, or when you don't want the registry to need knowledge of what objects/classes are in the system.
