> How do you feel about the saying that code itself should be as good as documentation?

Not him, but I'll take a crack at it: adorable, high-minded, and wrong. Most people are not going to walk through your code to grasp it in its entirety; design, and document, accordingly.

At the very least, you should have exhaustive, well-considered, commented unit and integration tests to demonstrate its use cases and (foreseeable) failure modes.
