Sets are stored in a very specific way that enables intersection to be fast - proportional to the size of the smaller set.
Intersecting arbitrary sequences can't be done particularly efficiently. If Clojure's intersection worked on sequences (perhaps by first converting to sets behind the scenes), people would get in the habit of passing sequences to intersection and would be surprised by the gross inefficiency of their code. Clojure forces you to choose the right data structure for the task at hand. If you need to do a lot of intersections, choose sets from the start. --Mark -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
