anaphoric

Anaphoric conditional forms for racket:

(aif (member 'a lst)
  (displayln it)
  (displayln "not found")) ;; Can't use "it" in the else clause.

(awhen (member 'a lst)
  (displayln it))

(acond
  [(member 'a lst) (displayln it)]
  [(member 'b lst) (displayln it)]
  [else (displayln "not found")]) ;; Can't use "it" in the else clause.

This package also provides hygienic versions:

(if-let [x (member 'a lst)]
  (displayln x)
  (displayln "not found")) ;; Can't use "x" in the else clause.

(when-let [x (member 'a lst)]
  (displayln it))

(cond-let x
  [(member 'a lst) (displayln x)]
  [(member 'b lst) (displayln x)]
  [else (displayln "not found")]) ;; Can't use "x" in the else clause.
