 I just love the new syntax. I assume select will continue to work as 
usual, for old code and for use cases where it works better. The _ARG 
name makes the parameter name for the main chunk consistent with Lua 
_NAME practice, a good change. Any code broken by this last change 
should be an easy fix: a simple search and replace.
