Thanks hippo,
I agree that the 'rules' are fast and far between for private subs. My private subs are, well, I wouldn't go as far as to say completely 'eloquent', but are typically self-documenting, especially for myself or any collaborators six months down-the-road.
That said, sometime's I'll add a specific section of documentation in POD (or otherwise) that doesn't exactly list/describe the sub in question, but does include developer-exclusive information in documentation that if they get deep enough, will find and be able to understand what private subs are required by higher-level ones, and easily (hopefully) figure out how they hang together.
