The following trivial code generates a reflection warning for the call
to hashCode:
(set! *warn-on-reflection* true)
(defn foo [o]
(.hashCode o))
It's easy to fix:
(defn foo [#^Object o]
(.hashCode o))
but I don't understand why a type hint for java.lang.Object could ever
be necessary. My understanding is (was?) that java.lang.Object is the
default type for all function arguments in Clojure. Am I wrong?
