This is really cool. I know Lua is a commonly embedded language for plugins and stuff. So now that we can support Lua powered extensions for web apps, I'd like to add to the list of naive questions here, coming from someone who's never used the language. What benefits does Lua provide over other langs for such a purpose? Is it the ecosystem of libraries that makes it unique in that respect? Or the actual language lends itself better for user scripting over, say, running JS code through JS-interpreter or just eval-ing validated JS code directly.
