Advice on using Lua for game scripting

[Jason White <whitewaterssoftwareinfo@...>]

Hello Lua mailing list, I am trying to add scripting support to a game
I'm writing. If I have 2 functions `init` and `update` in a script
plus a few global variables. I want to run multiple instances of this
script within the game. How could I do that without name space
conflicts ? I have a few ideas about doing this* but I'd like advise
on what the "best" way would be to do this without making the scripter
jump through too many hoops since I'm fairly new to Lua.

*storing the program in a table in another table
 or just purely functional programming
