Hi,
I have a short question, why map builds up a LazySeq instead of an input
collection as found below:
user=> (type (map #(mod % 3) #{3 6}))
clojure.lang.LazySeq
user=> (type (map #(mod % 3) '(3 6)))
clojure.lang.LazySeq
user=> (type (map #(mod % 3) [3 6]))
clojure.lang.LazySeq
user=> (type (map #(mod (% 1) 3) {:a 3, :b 6}))
clojure.lang.LazySeq
One would expect to "(map #(mod % 3) #{3 6})" evaluate into "#{0}". Is it
arbitrary decision or there is a theory behind it?
Best,
Andy
