No matter how many times I try to read that GoF stuff, I can't understand it.
But I hope that if we start with something that I certainly do understand and
feel sure you will too--i.e., commit f27b89f1--then you'll be able to show me
how intruding this control structure into page_with_tabular_report::render()
(as I hope we can do) would constitute this kind of "design pattern".
