user=> (doc count) ------------------------- clojure.core/count ([coll]) Returns the number of items in the collection. (count nil) returns 0. Also works on strings, arrays, and Java Collections and Maps Note how the name and docs both cleverly avoid use of the words "size" or "length", to help the function remain undiscovered by searches through the source code and by uses of find-doc. --Chouser --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
