Example
There's no built in way to search a list for a particular item. However Programming in Lua shows how you might build a set that can help:
function Set (list)
local set = {}
for _, l in ipairs(list) do set[l] = true end
return set
end
Then you can put your list in the Set and test for membership:
local items = Set { "apple", "orange", "pear", "banana" }
if items["orange"] then
-- do something
end
