[Tongue in cheek]  I hope Taco isn't reading this, because his view is:
    JavaScript is *way* off topic for this list.
and he might think the same about Emacs Lisp.

Seriously, it is a good suggestion.  If not an example to follow, it can 
be an example to learn from.  (And in my view the same goes for JavaScript.)
