No, it's not. As you were told multiple times by now, Scheme already has syntactic sugar for multiple constructs. 'x is (quote x), and (quote x) is (quote . (x . ())).

No, it doesn't. What makes Lisp Lisp is the ability to easily represent a program in the language's primary data structure and manipulate it. Infix syntax doesn't change that, it just makes things more readable. Again, you were told this multiple times, so I don't even know why I repeat it again. It's really a waste of time to argue with a stick-in-the-mud like you.
