Further thoughts on indexes, it seem unavoidable that index zero must exist to position yourself before something start, it is questionable if one should allow it to hold a value though. So you can position yourself at index zero but as soon you start to push things in to array they will start at index one.

The whole thing with start and end seem a pretty weird and lose concepts, is start before the first element or is start the first element. It seem we could have a list but not selected any of its element, so zero seem necessary in an array index???

But i do not think it "should" hold any data?
