Ah, ok. Looks nice. Btw:

  function pack(...)
    return arg
  end

  t = pack()

  print(t.n) ---> "0"


Is the arg.n field inside vararg functions by design?

So the "only" problem left is that arrays with holes are not smart and I
have to handle the array length myself?

As I seen, unpack() can handle explicit sized arrays now.
