Finding the right function in the doc admittedly takes a little practice. I've learned gradually, that Clojure pretty much has all its bases covered though. You just need to find the function. And this forum is filled with very helpful and friendly people, who will tell you the function name, if you describe the behavior you want, and if you ask nicely. "assoc-in" and "update-in" were the two functions that I needed help finding when I started. -Patrick --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
