// The callback takes the current collection being iterated, as well as the
// offset of that collection from the beginning of the starting collection.
//
// The callback returns a completion flag. It should return false to keep
// iterating, or true to stop iteration. The return value of
// VisitClassHierarchy() will be that of the last executed callback.
