nrepl.el: how to eval clojure buffer form to nrepl buffer instead of echo area?

Question

I\'m using nrepl.el from git (0.1.6-preview, via el-get recipe), and I would like clojure buffer evals: C-x C-e, C-M-x, C-c C-r for form, top-level form and region respectively,

Here is a version that also sends errors to the correct windows:

(defun my-nrepl-handler (buffer)
  "Make an interactive eval handler for buffer, but emit the value or out to the repl, not the minibuffer."
  (nrepl-make-response-handler buffer
                               (lambda (buffer value)
                                 (progn
                                   (nrepl-emit-result (nrepl-current-repl-buffer) value t)
                                   (nrepl-emit-prompt (nrepl-current-repl-buffer))))
                               (lambda (buffer out)
                                 (nrepl-emit-interactive-output out)
                                 (nrepl-emit-prompt (nrepl-current-repl-buffer)))
                               (lambda (buffer err)
                                 (message "%s" err)
                                 (nrepl-highlight-compilation-errors buffer err))
                               (lambda (buffer)
                                 (nrepl-emit-prompt buffer))))

(defun my-interactive-eval-to-repl (form)
  "Evaluate the given FORM and print value in the repl."
  (remove-overlays (point-min) (point-max) 'nrepl-note-p t)
  (let ((buffer (current-buffer)))
    (nrepl-send-string form (my-nrepl-handler buffer) (nrepl-current-ns))))

(defun my-eval-last-expression-to-repl ()
  (interactive)
  (my-interactive-eval-to-repl (nrepl-last-expression)))

(eval-after-load 'nrepl
  '(progn 
     (define-key nrepl-interaction-mode-map (kbd "C-x C-e") 'my-eval-last-expression-to-repl)))
