// There are 12 list iterator classes.
//
// WCValSListIter, WCValDListIter, WCPtrSListIter, WCPtrDListIter,
// WCIsvSListIter and WCIsvDListIter iterate only NON-CONSTANT lists.
// For example, to iterate a non-constant WCValSList, use the WCValSListIter
// class.
//
// WCValConstSListIter, WCValConstDListIter, WCPtrConstSListIter,
// WCPtrConstDListIter, WCIsvConstSListIter and WCIsvConstDListIter iterate
// either constant or non-consant lists.  The insert and append member
// functions are private to these iterator classes.
// For example, to iterate a constant WCIsvDList, use the
// WCIsvConstDListIter class.
