;; Advice: Do not call intersection with non-set arguments.  If you
Shoes slip Blue Bathroom Slippers Sandal House Anti Couples Men Indoor Women's Unisex Fnwq0WO;; are concerned that you may be unintentionally doing so, and want an
;; exception to be thrown if you do, consider using the library
;; funjible (https://github.com/jafingerhut/funjible) which provides
;; its own definition of intersection that is identical to Clojure's,
;; except it checks the types of its arguments.

;; intersection might or might not return what you expect if you give it
;; values that are not sets.  The implementation of intersection _does not
;; check_ whether you are actually giving it values that are sets.  It
;; _assumes_ so.

;; It is possible that intersection _might_ throw an exception if you
;; give it a non-set as an argument:
user=> (intersection #{1 3 Men's Gray Shoes Generic Moccasin gommino Loafer 5} [2 4])
ClassCastException clojure.lang.PersistentVector cannot be cast to clojure.lang.IPersistentSet  clojure.core/disj (core.clj:1517)

;; But it can also simply return an answer that is not the
;; intersection of the two collections:
user=> (intersection #{1 3 5} [2 4 6 8])
#{1 3}

;; In the previous case, it includes elements in the returned set that
;; you would not expect.  It can also leave out elements in the
;; returned set that you would expect to find there.
user=> (intersection #{"1" "3" "5"} ["1" "3" "5" "7"])
#{}

;; Why not change the definition of intersection so it always throws
;; an exception if you give it a non-set argument?  I would guess that
Moccasin Shoes Generic Men's Gray gommino Loafer ;; the primary reason is that the extra run-time type checks would
;; slow intersection down by an amount that the Clojure core team does
;; not want everyone to have to pay on every such call.
