Re: doall

Hi Renata, The problem with your code is that it is using *map* at the top level, which is a function that returns a lazy sequence. You are asking clojure to do something like: *Take each number n in inviteds and create a sequence of hash maps, where each hash map has n as a key and 1 as it's val

Re: Is there an easy way for s/keys spec to work against both qualified/unqualiffied keys at the same time?

Hi, You can achieve that using *spec/or*: (s/def ::map-with-numbers (s/or :qualified ::map-with-numbers1 :unqualified ::map-with-numbers2)) (s/valid? ::map-with-numbers {::some-number 3}) => true (s/valid? ::map-with-numbers {:some-number 3}) => true ​ Cheers, Mauricio -- You receive

Re: When to prefer keywords as functions?

Keywords can be used as a function with a map, so the keyword will search for itself in the map. Take a look at http://clojure.org/data_structures#Data%20Structures-Keywords In the case of the "ns" form, as James pointed out, what is happening is not a function call. ns is a macro and as such that

For updating the value of a map given a key you can use update-in: user> (update-in {1 [11]} [1] conj 22) {1 [11 22]} Now, to handle the case when the key is not present, you can use fnil: user> (update-in {} [1] (fnil conj []) 22) {1 [22]} ​ Cheers, Mauricio -- You received this message becau

Re: range-sum

My guess is that when using a rest-param a call to next is involved thus realizing two elements of the sequence. A call to rest only realizes the first element: user> (defn f [x] (println x) x) #'user/f user> (defn s [n] (lazy-seq (cons (f n) (s (inc n) #'user/s user> (def t (rest (s 0))) 0 #'
