Sure, to get a very basic REPL in Emacs is simple:

;; Because we use `loop' for the looks of it:
(require 'cl)

(let* ((buffer (generate-new-buffer "*tmp*"))
       (standard-output buffer))
  (switch-to-buffer buffer)
  ;; The REPL:
  (loop (print (eval (read)))))

The extra code in ielm is to get something a tiny little bit more
comfortable.
