Heh why do people use println while prn exists?

Why use any of those when you have cider?

@urbanslug: try (prn "ClojureScript is" 5 "years old.") vs. (println "ClojureScript is" 5 "years old.").

@roberto: How does cider help this?

mfikes: playing with migrating from lein to boot so really can’t get a repl but I assume the first fails.

@urbanslug: (You should be able to type lein repl in a directory without a project.clj whenever you want a REPL.)

hmmmm cool

@urbanslug: I'd also recommend doing doc on each; you'll gain insight into the rationale for each. :)

@mfikes: Thanks a ton

Still new to this game

@urbanslug: No problem. That's a perceptive question for someone new to this. :)

Cider debugger helps with that

So, I thought I understood how destructuring works, but then I ran across this (http://stackoverflow.com/questions/3208347/how-to-create-default-value-for-function-argument-in-clojure) question. I tried running Matthew Gilliard's answer:

(defn string->integer [s & {:keys [base] :or {base 10}}]
    (Integer/parseInt s base))

Were positional optional argument defaults removed or changed between the answer (Dec '11) and now?

Just realized I had misread something.
