The function can be anonymous:

  string.dump(function() return  { "one", "two", "three" } end)

I usually generate data with other languages and feed them to lua.
Simple shell example:

  cat <<EOS | luac -o data.luac -
  do
   return { "one", "two", "three" }
  end
  EOS

  lua -e 'print(dofile("data.luac")[1])'
