's help I've added some help text about the Lua enhancements we made to the Gideros version of Lua...http://docs.giderosmobile.com/reference/enhancement
Most of these enhancements have been made to make games run faster in Gideros Lua vs other versions of Lua. We did this by adding operators to take the place of commonly used functions or actions that your code performs frequently.
Other advantages are less typing, easier to read code (sometimes possibly harder too!), and greater protection from others de-compiling your code.
