NOTE: This mail was sent outside the group for some reason, so I am
(re)posting it here, so that other people can benefit. By the way, Peter
replied that this solved the problem he had with snippets in javascript-mode.

Peter,

there were indeed some flaws in that code. Should've checked with emacs -Q.
Well, I have trimmed my .emacs down to the following bare minimum, which
really works for me (my emacs version is "GNU Emacs 22.1.1 (i486-pc-linux-gnu,
X toolkit, Xaw3d scroll bars) of 2007-11-06 on terranova, modified by
Ubuntu"):

;;this is where my snippet.el and javascript.el reside
(add-to-list 'load-path "~/.emacs.d/nxml/related")

(autoload 'javascript-mode "javascript" nil t)
(add-to-list 'auto-mode-alist '("\\.js\\'" . javascript-mode))
(require 'snippet)

;; Apparently the abbrev-table *should* be bound, for
;; snippet-with-abbrev-table not to blurb: 

(define-abbrev-table 'javascript-mode-abbrev-table ())

;; Yup, here was a quote missing
(snippet-with-abbrev-table
 'javascript-mode-abbrev-table
 ("for" .  "for $${element} in $${sequence}:")
 ("im"  .  "import $$")
 ("if"  .  "if $${True}:")
 ("wh"  .  "while $${True}:"))

(add-hook 'javascript-mode-hook
         (lambda ()
           (abbrev-mode 1)
           ;; Here really should NOT be a quote:
           (setq local-abbrev-table javascript-mode-abbrev-table)))

Perhaps something in python-mode sets the correct abbrev-table already. By the
way, what strange dialect of JavaScript is that ;) ?
