Using table.insert and table.remove is efficient only if you are using the 
list in lifo (stack) mode, else it can become deadly slow.
Roberto's book ("Programming in Lua") shows a better way to build lists, using 
unbounded arrays. I'd suggest to Phil a reading of that book, to get a better 
understanding of the language.
