I've been using lua now for some years and I never had the need for
this. Could you elaborate on why you want to use this? It should be
possible to put your code in a module which is always called by
require(). If you also want to have a standalone version of this
module, just use a main file where you require this module and execute
the needed code. 

Kind regards,
