It's not clear that it has one.  Many of the procedures in the
standard library are implemented in C -- for example, +.  These
primitive procedures don't have Scheme bodies to display.  Also, the
body of even a scheme-defined procedure may never have been written by
the programmer.  For example, consider this tiny procedure:

(define myproc
  (let ((+ -) (a 3))
    (lambda (x) (+ x a))))

What should be printed as its body?  Should it be different from the
body of this procedure below?

(define myproc
  ((lambda (+ a)
    (lambda (x) (+ x a)))
  - 3))
