I can see how that could be confusing at first. You might think an IPersistentSet is a subclass of java.util.Set and that set? asks if it is a java.util.Set. Then if you wanted to know if if something is an IPersistentSet, you might have to call "ipset?" But another name for that would be "clojure-base-set". But then if you think about it, "clojure-base-set" or even "clojure-set" would be redundant. Afterall, we're looking at clojure code. I wonder though if you can call instanceof from clojure to test Java types. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
