I was perusing the manual today and noticed the various iterators. To me, it seems like they are all somewhat pointless; I don\'t see a reason to use them unless you prefer
Iterators are just as fast as anything else, but with an easier interface and perhaps more verbage to wrap it in. However, the main advantage is not what you may need right now, but how you can extend them to deal with your future problems (and they will come!), and that is what we old boys call "saving your future ass". :)
