I created this trivial function which does this without the instant visual 
feedback, but at least it spares me copying the text, going back
to the beginning of buffer, pasting it to the replace prompt and when all
instances are replaced then going back to the place where the whole
thing is started:

(defun my-replace-region ()
  (interactive)
  (unless (use-region-p)
    (error "no region"))
  (let ((what (buffer-substring-no-properties
               (region-beginning) (region-end)))
        (replacement (read-string "replace with: ")))
    (save-excursion
      (goto-char (point-min))
      (while (search-forward what nil t)
        (replace-match replacement)))))

The live feedback would be better, because it's more fancy and the
user can see an instant confirmation of the replacements during typing
if more than one of them is visible on the screen.
