Hello, I think you're talking past each other a little bit. Andy is saying that the Scheme standard doesn't specify eq? on numbers. David is saying that an object should always be eq? to itself, no matter what object.
I believe David's claim is that Guile should guarantee that a variable is eq? to itself, even though the standard doesn't. I don't know what the right answer is, but I think that's what this discussion should be about.
