I don't know what this fork changes, but I love how many game engines will take lua and expand it to fit their exact needs like this.
Very few scripting languages make it as easy to do as lua.
This is an interesting related project:
It compiles down to lua, and really beefs everything up. Interface is super nice too. You just put `require "moonscript"` at the top of the file and you're done, now just write your code in moon script.
