;;
;; Basic usage:
;;
;; (with-cache (:hash-table :test #'equal :key #'cons)
;; (defun add (a b)
;; (+ a b)))
;; This function caches the returned values for already passed combinations of
;; arguments. In this case ADD stores the key (CONS A B) and the returned value
;; to a hash-table when (ADD A B) is evaluated for the first time. ADD returns
;; the stored value when it is called with the same arguments (w.r.t. EQUAL)
;; again.
;;
;; The storage for cache can be hash-table or array. Let's see an example for
;; array:
;; (with-cache (:array (10 20 30) :initial-element -1 :element-type 'fixnum)
;; (defun foo (a b c) ... ))
;; This form stores the value of FOO in an array created by (make-array (list 10
;; 20 30) :initial-element -1 :element-type 'fixnum). Note that INITIAL-ELEMENT
;; must always be given here as it is used as the flag expressing `not yet
;; stored'. (Therefore INITIAL-ELEMENT should be a value FOO never takes.)
;;
;; If you want to ignore some arguments, you can put `*' in dimensions:
;; (with-cache (:array (10 10 * 10) :initial-element -1)
;; (defun foo (a b c d) ...)) ; then C is ignored when querying or storing cache
;;
;; Available definition forms in WITH-CACHE are DEFUN, LABELS, FLET, and
;; SB-INT:NAMED-LET.
;;
;; You can trace the memoized function by :TRACE option:
;; (with-cache (:array (10 10) :initial-element -1 :trace t)
;; (defun foo (x y) ...))
;; Then FOO is traced as with CL:TRACE.
;;
;; FIXME: *RECURSION-DEPTH* should be included within the macro.
