scope, design patterns?

["Patrick Mc(avery" <spell_gooder_now@...>]

This question may not have an answer!.....

I've achieved good results with my Lua code in a real world sense but 
that is only due to a lack of competition, my code has been a disgrace.

I am starting a new project and want to minimize globals and use the 
same sort of strategies that other list members use.

I fould this page on the wiki:
http://lua-users.org/wiki/LuaScopingDiscussion

but it seems quite out of date according to this note:
""Comments on this page refer to a quite old version of Lua (2001 era) 
that had more limited lexical scoping and presumably non-complete 
closure support. Many of these comments don't apply on recent versions 
of Lua."""


I understand closure, functions and other tables as table values, local 
variables etc.. it's just that I only know a limited number of ways to 
assemble them for privacy.

Is there something out there akin to a design patterns tutorial for Lua 
that illustrates various privacy patterns?

Hope everyone is enjoying time with their families this time of year-Patrick
