I like the concept of focusing on working with file iterators and file
processing concepts like head, tail and cat as a concrete example -
starting by designing a clean solution to a specific problem and
generalising from there is almost always a much better approach than
trying to design the general case without reference to specific
examples.

Cheers,
Nick.
