Is x86 machine code homoiconic? Or, generalizing, is any/all VN-arch machine code homoiconic? It's pretty obvious that (pure) Harvard-arch machine code isn't, but VN? (I'm talking about the interface here. Yes, I know that modern x86 processors are not really VN-arch internally. But they present the interface of a VN-arch processor to the programmer, which is what I mean here.)
