(require "add-with-memory.rkt")

(define + add)

;; We can use the new + here in the file, or in the REPL after we run this
;; file.

;; -------------------------------------------------------------------------
;; If we know we want to define + to be the imported add function, there is
;; an alternative way to import the function:
;;    (require (rename-in "add-with-memory.rkt" (add +)))
;;
;; Doing so affects the meaning of + only in this file.
;;
;; 'require' offers a number of handy ways to import functions from another
;; file, much as Python's import feature does.
;;
;; 'provide' also offers a number of handy ways to export a file, as we saw
;; in the comment at the end of "add-with-memory.rkt".
