A function guaranteed to return True when given a winning lottery-number

100% guaranteed to return True when passed a winning number:

(defun return-true-when-winning-number (input-number)
    'true)

It also returns True when given a non-winning number, but I’m sure I’ll iron out that bug sometime soon.
