We have "wp:Lua" as a start, but we will expect computer programmers as the first group, and yet try to reach a point where "markup users" can help to adjust the Lua script source code. Because of the base complexity, the related JavaScript and toolserver people will be the most likely to work with Lua at first. However, there will be more Lua-based templates which act as "super-templates" which the markup users can combine as powerful tools. -  

 Lua readership has doubled from 2009/2010: I was looking back to Lua readership in 2009, which I had forgotten was an issue back then, so no wonder the installation of Lua seemed like a will-it-ever-arrive frustration. Anyway, back in 2009, there were ~640 Lua pageviews per day, but later increased in 2010 to 720/day, and now we have ~1,280/day. Compare the growth of January pageview graphs in years 2009-2013:

 Even though the active editors have maintained a relatively stable article-edit rate for the past 3 years, the reader interest in article "Lua (programming language)" has grown to double during those years. We might even attract users who prefer helping to improve Lua modules, rather than articles, and could become more future developers to accelerate other software improvements to simplify the editing of articles. I had not realized how a thousand people a day read about Lua here. -
