Very funny example. But is this just a fun exercise or is there more to it? Is circularity the same as self-reflection or is this some ideal case in a thought experiment?

What happens when it is translated into a lesson plan? I once ran a session on problem-based learning where the problem-based learning was the problem set to the group. By the end of 90 minutes everyone, including me was thoroughly confused. I've heard of similar experiences at Glasgow medical school. When I did that session again, I set a non-educational problem and the results were much more encouraging.

What about initiatives like 'personalised learning' which basically make each curriculum to be at least partly about itself (sort of a meta curriculum).
