Occasionally, I want to map a collection of seqs to their is-empty or is-not-empty status (e.g. true / false). And the helpfile of empty? puts me on the wrong leg occasionally.
clojure.core/ empty? ([coll]) Returns true if coll has no items - same as (not (seq coll)). Please use the idiom (seq x) rather than (not (empty? x)) If I decide I specifically want true or false returned, and not (content of seq) / false, I sometimes pick up seq?, not realizing that it will always return true on both empty and filled seqs. Made the mistake a few times so far, and I blame it on this helpfile putting me on the wrong leg :-). Perhaps we could add a short line after the last saying ", unless you specifically need true/false returned, rather than content/false." -- You received this message because you are subscribed to the Google Groups "Clojure" group.
