object serialization

Hi,

what would be the simple and elegant way to do serialization /
persistance of a specific luabind::object?

I only need to save numeric and string values and tables of them. I
was thinking about recursive visitation like so:

void visit(const luabind::object& obj)
{
  using namespace luabind;

  if (type(obj) == LUA_TTABLE)
  {
    cout << "{" << endl;

    for (luabind::iterator it(obj); it != luabind::iterator(); ++it)
    {
      if (type(it.key()) == LUA_TSTRING)
      {
        if (type(*it) != LUA_TTABLE)
        {
          cout << it.key() << " = " << *it << endl;
        }
        else
        {
          visit(*it);
        }
      }
    }

    cout << "}" << endl;
  }
}

cout is used here to print name/value pairs but in real case actual
persistance code would be used.

Am I going the right way?

Cheers,
Szymon
