I don't know why you have to "guess" something as obvious as this, but
have at it.

stuff = {"red", "green", "blue"}
for _, arg in pairs(stuff) do
    -- arg is no longer the "commandline argument vector" here.
    -- anyone who has mastered the Lua tutorial should know that.
    print("stuff:", arg)

-- but since 'arg' is local to the for loop, it is only overwritten
__inside__ the for loop.
for _, s in pairs(arg) do print("arg:", s) end
