I did not say anything about s-expressions. I said "homoiconicity". S-expressions are not an absolute requirement for homoiconic features. You keep poking me with your "knowledge" as if I'm trying to sell you snake oil and you feel obligated to defend and retaliate. I don't need to prove anything to you, I'm not your ignorant professor attempting to instil you with some defunct truths that exist solely in my head. Do your own research. Or don't, who cares.
