10.2.19 set | Function
  Syntax: set symbol value value Arguments and Values: symbol - a symbol. value - an object. Description: set changes the contents of the value cell of symbol to the given value.
      (set symbol value) ==(setf (symbol-value symbol) value)
  Examples:
       (setf (symbol-value 'n) 1)  1
       (set 'n 2)  2
       (symbol-value 'n)  2
       (let ((n 3))
         (declare (special n))
         (setq n (+ n 1))
         (setf (symbol-value 'n) (* n 10))
         (set 'n (+ (symbol-value 'n) n))
         n)  80
       n  2
       (let ((n 3))
         (setq n (+ n 1))
         (setf (symbol-value 'n) (* n 10))
         (set 'n (+ (symbol-value 'n) n))
         n)  4
       n  44
       (defvar *n* 2)
       (let ((*n* 3))
         (setq *n* (+ *n* 1))
         (setf (symbol-value '*n*) (* *n* 10))
         (set '*n* (+ (symbol-value '*n*) *n*))
         *n*)  80
        *n*  2
       (defvar *even-count* 0)  *EVEN-COUNT*
       (defvar *odd-count* 0)  *ODD-COUNT*
       (defun tally-list (list)
         (dolist (element list)
           (set (if (evenp element) '*even-count* '*odd-count*)
                (+ element (if (evenp element) *even-count* *odd-count*)))))
       (tally-list '(1 9 4 3 2 7))   NIL
       *even-count*  6
       *odd-count*  20
Side Effects: The value of symbol is changed. See Also: setq, progv, symbol-value Notes: The function set is deprecated. set cannot change the value of a lexical variable. Allegro CL Implementation Details: None.
