Re: Rabid wild animals in my clojure argument lists, code gets infected.

If you have assertions enabled, you can declare (defn foo [a b & {:keys [c d]}] {:pre [c d]} 1) to make sure that c and d are not nil (defn foo [a b & {:keys [c d] :as m}] {:pre [(every? m [:c :d]]} 1) to make sure that c and d are contained and (defn foo [a b & {:keys [c d] :as m}] {:pre

Re: Rabid wild animals in my clojure argument lists, code gets infected.

Sorry, I answered too quickly: The second one was wrong - this one ensures c and d are contained. (defn foo [a b & {:keys [c d] :as m}] {:pre [(every? (partial contains? m) [:c :d]]} 1) And the last one was un-idiomatic - this one checks whether only c and d are contained. (defn foo [a b & {:

map over a Map with conditional conj

Hi, I find myself repeating a certain pattern from time to time. I have a map like this: {:answer_correct_1 2 :answer_correct_3 4 :foo "bar"} There is a hidden index answer_correct_idx which might range from 1 to x. So, what I want is to "iterate" over the map and produce a vec of maps given s

Sven, To me, the keep version would be a lot more readable if it were creating a literal map in a fn. I think (for) is almost always the right thing. It's not as fun to write, but much easier to read: (for [i (range 1 11) :let [id (keyword (str "answer_correct_" i))] :when (params i
