Re: class of java array

e question, "How do I determine what type of object is inside an array?" I interpreted the original question to be, "How do I distinguish Arrays from other kinds of objects?" Here's one way to do that: user=> (.isArray (class (into-array ["a"]))) true user=>

Re: What is Clojure NOT good for?

My wife and I both write software. She think's I'm insane to use Clojure because the poor sucker who has to maintain what I've written will be uncomfortable with anything other than Java. (She may also think the poor sucker won't want to deal with my dubious programming skills, but that's anothe
