Well, what would you expect? Ranges are consumed when you iterate over them. 
So, if an container is a range, it will be consumed when you iterate over it. 
That's the way that it _has_ to work given how ranges work, and that's why you 
overload opSlice to return a range which is iterated over rather than making 
the container itself a range.
