Mmmh, if you only need references to subtables, you could do even better ...

$ cat > ref2.lua
local temp = {}
local function v( s )
  return function( t )
    if temp[ s ] then
      for k,v in pairs( t ) do
        temp[ s ][ k ] = v
      end
    else
      temp[ s ] = t
    end
    return temp[ s ]
  end
end
local function r( s )
  if not temp[ s ] then
    temp[ s ] = {}
  end
  return temp[ s ]
end

a = {
  one = v"one"{
    a = 1,
    b = r"two"
  },
  two = v"two"{
    a = 1,
    b = r"one"
  }
}

print( a.two.b.b.b.b.b.b.a )
^D
