Opposite of unpack() in lua 5.0?

[Michael Roth <mroth@...>]

Hello,

I'm new to lua. I would like to do the opposite of unpack(). Example:

function test()
  return 1, 2, 3
end

t = pack(test())

print(t[1])


But in Lua 5.0 there isn't a pack() function, right? Why not? other 
solutions possible?
