Have you used Lua for any projects? If so, what was the project and how did you find Lua compared to other languages?

I recently got back into programming via Lua, which is a language used by various mods in Minecraft and was delighted to find a wide range of libraries and cross language support available for it. It may be only 28 on the TIOBE survey, but the language is top notch and extremely simple to learn and utilize.

So what are your thoughts?
