| ANSI Common Lisp 10 Symbols 10.2 Dictionary of Symbols
10.2.13 symbol-plist | Accessor
  Syntax: symbol-plist symbol plist (setf (symbol-plist symbol) new-plist) Arguments and Values: symbol - a symbol. plist, new-plist - a property list. Description: Accesses the property list of symbol. Examples:
       (setq sym (gensym))  #:G9723
       (symbol-plist sym)  ()
       (setf (get sym 'prop1) 'val1)   VAL1
       (symbol-plist sym)  (PROP1 VAL1)
       (setf (get sym 'prop2) 'val2)   VAL2
       (symbol-plist sym)  (PROP2 VAL2 PROP1 VAL1)
       (setf (symbol-plist sym) (list 'prop3 'val3))  (PROP3 VAL3)
       (symbol-plist sym)  (PROP3 VAL3)
Exceptional Situations: Should signal an error of type type-error if symbol is not a symbol. See Also: get, remprop Notes: The use of setf should be avoided, since a symbol's property list is a global resource that can contain information established and depended upon by unrelated programs in the same Lisp image. Allegro CL Implementation Details: None.
