No such animal. You're looking at a MediaWiki extension (written in PHP) with a persistent database (MySQL is traditionally paired here). Way beyond the scope of Scribunto (the extension that processes Lua). It's a templating language. Unlike full Lua, it's just for templating, not for making extensions.
