(void?) in DrRacket

Question

How to use the built-in function void?. The code

(void? void)

returns #f. Deeply confused.

Appreciate your help. And apparently I have to type more stuff in order to get it posted

Answer 1

void is a function that returns the special constant #<void>. So the function itself is not void, but its result is:

(void? (void))

produces #t. See http://docs.racket-lang.org/guide/void_undefined.html and/or http://docs.racket-lang.org/reference/void.html.
