OK, true. We could then use 
 CSwordVerseKey CSwordVerseKey::NextVerse() 
[example like above]

but it might be even better to use
 void CSwordVerseKey::getNextVerse()
and then like this
 CSwordVerseKey *key1 = new CSwordVerseKey(m_module);
 CSwordVerseKey *key2 = new CSwordVerseKey(m_module);
 ...
 key2 = key1;
 key2->getNextVerse();
1 line longer, but much more safe and simple.
