Good point:

I'm evaluating whether to use the minor mode approach. Because the
current mapping in a 'dolist operating on a (sequence . function)
alist, (hence eliminating redundant calls) it is easy enough to
switch over. 

however, since I also have a hook function for python-mode, a quick
fix is something like

(defun tj-python-mode-keys ()
  "Additional key bindings and rebindings for python-mode
  functions."
  ;; the following overrides of all of Jurgen's bindings
  ;; that conflict with mine.
  (define-key elpy-mode-map (kbd "C-c s") nil)
  (define-key elpy-mode-map (kbd "<C-return>") nil)
  (define-key elpy-mode-map (kbd "<S-return>") nil)
  (define-key elpy-mode-map (kbd "<C-S-return>") nil)
  (define-key elpy-mode-map (kbd "C-c C-b") nil)
  ; ...
  )
;; This code is after elpy is loaded and precedes my global
;; bindings.   

:) so many choices ...

thanks very much
