you can't know what the output will be until you run it.

Yes! That's a better way of saying what I like about it.

You could also simply do ...

Yes, that's a lot simpler, and it obviously requires the same brute force approach to produce. Still, I really like the idea of having it use itself to produce its output, but I'm not sure why. If I weren't shooting for that specifically, generation would have been easier. An early version did not vary the delimiters, but there was too much static text producing the same results from iteration to iteration.
