Thanks for the shoutout @olivermt!
This is the talk if you’re interested. We actually built a visual editor that targets Lua as its compilation target, and then we execute that Lua. As Oliver mentioned, this provides a nice way to sandbox the user generated “code” while providing clean interfaces, loops, etc. This removes a lot of ad-hoc mechanisms that would be required otherwise, and provides a nice level of abstraction to remove implementaiton details, that all sits under the Lua APIs (which are implemented mostly in Elixir!)
