set vs hash-set

[Alan Thompson]

OK, this one has me stumped.  What is the difference between clojure.core/set and clojure.core/hash-set  ???   The source code is almost identical.  Is one to be preferred over the other depending on circumstances?

Alan

(defn set
  "Returns a set of the distinct elements of coll."
  {:added "1.0"
   :static true}
  [coll] (clojure.lang.PersistentHashSet/create (seq coll)))


(defn hash-set
  "Returns a new hash set with supplied keys."
  {:added "1.0"
   :static true}
  ([] #{})
  ([& keys]
   (clojure.lang.PersistentHashSet/createWithCheck keys)))

[Gal Dolber]

One takes a coll and the other a list of arguments

user=> (set [1 1])

#{1}

user=> (hash-set 1 1)

#{1}
