[snip] Page 24 contains: ill-conceived ability to implicitly convert arrays of derived types to arrays of base types. There only one problem with doing that that I can think of and that's the difference in sizes which would lead to operator++ for base array possibly pointing to the middle of an object of the derived type. However, couldn't that be overcome by wrapping the container in something that adjusted the operator++ to increment the pointer by the derived type size while returning a pointer to the base type? Also, the table on that page just mentions Array's. What about all other stl types which are implemented using pointers (like std::list). How would one know whether or not the list elements contained elements that pointed to the same list object; thereby leading to a circular reference. How would that be handled?
