[racket] why an implicit begin to encapsulate the template in syntax-case ?

(define-syntax test 

  (λ (stx) 

    (syntax-case stx () 

      [(_ a b)

       (define #'a #'b)])))

(test a 2) 

;begin (possibly implicit): no expression after a sequence of internal
definitions

;(begin (define #'a #'b))

 

If you can pinpoint the answer in the reference manual, I will appreciate
it. 

 

Thank you

 

André
