So I was messing around in Touch Lua (iOS app) and noticed how the unpack() finction seems to not exist (See picture).

I can't really come in contact with the app developers, so is there a possible way to make a new similar unpack function that does basically the same thing.

function unpack (t, i)
  i = i or 1
  if t[i] ~= nil then
    return t[i], unpack(t, i + 1)
  end
end
