> Well, I don't want to be a beginner for too long, :-) I am not a clojure beginner (though far from feeling I know all there is to learn about it). I have been using clojure for almost a year; my team has rebuilt the central part of our system (which is relied on by just about every other team where I work) out of clojure and have had it in production for 6 months. I've yet to even learn *how* to use defrecord, deftype & defprotocol. IMO, If you're not doing a lot of java interop (i.e. where your clojure code is being consumed by java clients) you might never need them. As someone who came from, C++, C# & Ruby (and a little Java) - i.e. OO - to clojure & FP, I *strongly* recommend that you take a project (preferably one that you aren't hanging your livelihood on, but trust me it's a real rush) and try *really* hard to solve your design problems just with maps, vectors and the other core data structures (I first tried this in ruby, btw - a great learning experience and gave me a strong appreciation for the optimizations that clojure provides to make such code practical). IOW: pretend for a project that OO doesn't exist. When you're done, you'll have learned a lot, you'll still have what you know about OO, and when you're done you'll have lost nothing except your time and your perspective. You'll be doing yourself an enormous disservice if you simply try to map clojure onto your current way of working/thinking. bill -- You received this message because you are subscribed to the Google Groups "Clojure" group.
