That's weird, not sure why you get ClassCastException and not the spec error of add1.
That said, you can not validate a lazy-seq without realizing it. You can use s/every? on big collections, that will sample x element and validate only those. So its normal for coll-of to realize the lazy-seq, as it is looping on all its elements and checking that they all conform. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
