Rich, I meant to corner you for a minute after your second talk, but you were pretty thoroughly cornered for all of clojure conj. Just curious: Do you subscribe to Linda Rising's suggestion that we could replace our caffeine intake with naps*? Or do you not find it as damaging as booze? -steve

I was seeking `interpose` function, thanks. But it still doesn't work for strings - they are not wrapped by "\"\. E.g. (apply str (interpose ", " (list 1 2 3 4 5))) ==> "1, 2, 3, 4, 5" and (apply str (interpose ", " (list "1" "2" "3" "4" "5"))) ==> "1, 2, 3, 4, 5" The problem is that applying

Fastest way to generate comma-separated list

Hi all, I work with a database and need a function, that will convert Clojure sequence to a string with a comma-separated elements. E.g., (comma-separated (list 1 2 3 4 5)) ==> "1, 2, 3, 4, 5" It must work with any data type - ints, strings, other lists, etc. E.g. for a list of strings it mu
