adopting analogies is a great way to learn, but i have been burned by
adopting ones that i mistakenly took to be more insightful (general)
than they actually were.  in this case, i might have as a newbie
(conjecture because i have forgotten the precise steps of my learning
process, unfortunately), taken the above to also imply that:

  (setq f '(+ 1 2 3))
  (funcall f)

would also be "valid", which it is not.  it certainly is valid when the
quoted object is a function, i'm not arguing against that.  i'm just
pointing out how easily i confuse myself w/ a little imprecision.
