Is Ruby an acceptable Lisp? It has everything you need except macros.
(module lithp racket/base
(require (for-syntax racket/base))
(provide #%module-begin #%datum quote
#%plain-lambda define-values λ
define #%app #%top)
(define-syntax (#%app stx)
(syntax-case stx ()
((#%app f x) #'(#%plain-app f x))
((#%app f x y ...) #'(#%app (#%app f x) y ...))))
(define-syntax (λ stx)
(syntax-case stx ()
((λ (x) . b)
#'(#%plain-lambda (x) . b))
((λ (x y ...) . b)
#'(#%plain-lambda (x) (λ (y ...) . b)))))
(define-syntax (define stx)
(syntax-case stx ()
((define (f x ...) . b)
#'(define f (λ (x ...) . b)))
((define x y)
#'(define-values (x) y)))))
