Lisp? no THANKS

I am make a new progrmming language based on the work of MCARTHY It is named

ГISP

Central idea is SYNTAX

(COND (a b) (c d) (e f))
is replaced by
(a → b, c → d, e → f)

GIve me OTHER ideas to replace all of lisp with SYNTAX thnk.
I await the reply..

<=> as a primitive operator, of course

(define (<=> a b)
 (cond
 ((< a b) true)
 ((= a b) true)
 ((> a b) true)
 (else false)))
