Hi,
a quick question:
user=> (keys {:a 1 :b 2})
(:a :b)
But
user=> (key {:a 1})
java.lang.ClassCastException: clojure.lang.PersistentArrayMap cannot
be cast to java.util.Map$Entry (NO_SOURCE_FILE:0)
I see defn key in core.clj, though.
What can be the correct usage of fn key, then?
thanks in advance,
-sun
