Is there interest in a clone_ptr class to supplement the current smart_ptr library? A clone_ptr is a smart pointer which performs a deep copy of the pointed-to object whenever the clone_ptr is copied. Also, the polymorphic type is maintained, eg: clone_ptr<Base> p(new Derived); clone_ptr<Base> p2; p2 = p; /* p and p2 now point to different Derived objects */ I am aware that there is a policy_ptr library being constructed which will probably provide the same functionality as this clone_ptr; however, when is this policy_ptr library scheduled to be completed? With cvs.sourceforge.netcurrently appearing to be down I've been unable to find accurate information on the status of this library, but with the complexity involved in creating such a versatile smart pointer, I imagine policy_ptr will still be under construction for some time; whereas a clone_ptr class could be written rather quickly, considering the simplicity of it and using the existing smart_ptr library as a guide.
