I like Iterable for the ease of use in a foreach loop. But there is a
risk it uses more memory than necessary. The pros for an Iterator is to
be able to stream the data without holding the whole structure in
memory. I don't know if that makes a real difference for your use case.
An Iterable than can only be iterated once is another solution.
