This helps, thanks.  Still, it feels weird that Emacs is oblivious to 
symbols even
in Emacs Lisp code, not to mention that C-M- chords aren't super 
comfortable.
So, since there is no option to customize this behaviour, I've written a 
snippet
of code to do so for any programming mode.  I would have preferred my 
code to
scan the syntax table and convert symbol constituents to word constituents,
but I have not been able to figure out quickly the format of syntax tables,
therefore I've resorted to manually listing non-word graphic characters.

(defun rr-symbol-constituent-p (^char)
   "Return non non nil if ^CHAR is a symbol constituent in the current 
buffer's
syntax table."
   (= (char-syntax ^char) ?_))

(defvar rr-graphic-non-word-char-list
   (string-to-list "!\"#$%&'()*+,-./:;<=>?@[\\]^_`{|}~")
   "List of characters besides letters and numbers that could be symbol
constituents according to syntax tables.")

(defun rr-symbols-to-words ()
   "Make symbols act as words in the current buffer's syntax table."
   (mapcar (lambda (^char)
             (when (rr-symbol-constituent-p ^char)
               (modify-syntax-entry ^char "w")))
           rr-graphic-non-word-char-list))

Cheers.
