I think if we are clear about it being an analogy we are on solid ground. But as soon as we start thinking pointers and references are the *same* thing we are in trouble, because now we can't see the differences anymore.

I think Date actually nails this issue. He says (roughly) that pointers add complexity but don't add any expressive power.
