string.gfind is really handy.

As an example, the question of iterating over a string which was 
floating around earlier could probably best be handled with:

for ch in string.gfind(str, ".") do
 -- handle a character
end

So put this in your startup:

function string.lines(str) return string.gfind(str, "[^\n]+") end

:)

Some time ago I put some other string-slinging examples, several taken 
from PIL, on the wiki: http://lua-users.org/wiki/StringRecipes
