Coming from the Ruby and JavaScript worlds, I am used to having functions that normalize their arguments, such as the "$" function in various JavaScript libraries. Other library functions tend to automatically call "$" for you, so you don't have to remember whether to do it or not.
One analog in Clojure is functions that work on seqs (or seq-ables). In general, I would rather not have to remember, and assume that most functions call seq internally if they need to. To make this concrete, should the following function from clojure.contrib.seq-utils call seq on its arg? As written, you cannot call it with an associative collection unless you remember to wrap it in a seq: (defn rand-elt "Return a random element of this seq" [s] (nth s (rand-int (count s)))) Stu --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
