That sounds useful. Could you pop it up in a tooltip?

What about using mouse pointer as a "secondary cursor", if we would like to see
some previous value, so we don't have to move cursor around:

(defun pointer (x y)
  (save-excursion
    (goto-char (window-start))
    (forward-line x)
    (when (> (- (line-end-position) (line-beginning-position)) y)
      (move-to-column y)
      (1- (point)))))

(defun symbol-value-under-pointer ()
  (interactive)
  (save-excursion
    (let ((pointer (mouse-position)))
    (goto-char (pointer (cddr pointer) (cadr pointer)))
    (let ((sym (intern-soft (current-word))))
      (when sym
        (message "%S: %S" sym (symbol-value sym)))))))

Could that be useful to have on a C-u C-u e?
