Thanks Meikel for your reply.
It wasn't clear on my example, but I wish to use *merge *inside my
create-map function. Do you think I should bind my hash-map to a let
variable first and then apply merge, or do you have another proposal? What
i mean is this:
(defn create-key-value [value]
(when (some-condition-true) {:extra-key value))
(defn create-map []
> (let [my-map {:foo "a" :bar "b"}]
> (merge my-map (create-key-value "some-value")))
Is the above "clojurish" or is there a better way? For example if the
my-map was a big hash-map, and not with just two pairs, wouldn't it be ugly
with the above way? or..it's just fine and no better way is possible?
