Description
user=> (= (sorted-set 1) #{:a})
ClassCastException java.lang.Long cannot be cast to clojure.lang.Keyword clojure.lang.Keyword.compareTo (Keyword.java:109)
but
user=> (= (sorted-set 1) :a)
false
also
user=> (get (sorted-set 1) :a 2)
ClassCastException java.lang.Long cannot be cast to clojure.lang.Keyword clojure.lang.Keyword.compareTo (Keyword.java:109)
PersistentVector also has the same problem.
user=> (compare [1] [:a])
java.lang.ClassCastException: clojure.lang.Keyword cannot be cast to java.lang.Number
The cause of this problem is that Util.compare() casts the second argument
to Number without checking its type when the first argument is a Number.
