We have been doing some work in Wikipedia lately and one of our favourite things to do is add templates to articles to make a point (just kidding, we really mean well). At the same time, proper citation formatting seems to be a constant struggle with a multitude of proposed solutions, some of which are very complicated to use. Our interest in these two aspects of editing lead us to read more of the technical references on Wikimedia (Wikipedia's software provider), where we began to see disturbing (to an expert in programming language theory, such as ourselves) template extensions such as control structures.

This led us to hypothesize that Wikimedia's template language had becoming Turing complete (the technical jargon for a full-powered programming language).
