* pointer-semantics or value-semantics and nullptr (brought up by Vincente)
- Should the COW-class be nullable? If not, then it should probably not be called cow_ptr. - This question has not been discussed to the end yet. Personally, I don't think that null-cow_ptrs are very useful.
* Different member and non-member functions (brought up by Vincente)
- relational operators (brought up by Vincente)
- It is not clear, whether operator==() on cow_ptrs should only compare pointers or also pointees. This would depend on whether the COW-class is considered a pointer or a genuine value.
If you choose for your class to have value semantics the relational operator should compare pointees. Vicente
