I would say, they treat nil as an empty sequence, which makes nil, effectively, a unit: (assoc nil :a :b) ; => {:a :b} (merge nil {:a :b}) ; => {:a :b} etc. On Wednesday, August 29, 2012 7:36:26 PM UTC+2, Moritz Ulrich wrote: > > This isn't true in Clojure: http://clojure.org/lisps > > However,

Calling flatten on anything that is not 'sequential?' returns an empty sequence: (flatten 1); => () (flatten "Hi"); => () With sets if feels somewhat strange: (flatten #{#{:a} #{:b :c}}); => () For some reason I expected #{#{:a} #{:b :c}} to equal #{:a :b :c}. Ok, the docstring says: "Takes
