It pointlessly refers to repeatedly and then returns a reference to the create-user function. Which is function and not a sequence, which is why you cannot take n from it. user=> (defn stream2 [] (repeatedly create-user)) > > This function invokes repeatedly with a reference to create-user and returns a lazy-sequence, which you can take n from. > In other words, what effect does wrapping the function body in quotes actually do? By quotes I assume you mean ()'s. The answer is above. in stream1 you are simply refering to functions. Without the ()'s you're not invoking anything. Compare: user> create-user #<user$create_user user$create_user@3f8ecde> to: user> (create-user) {:id 1} user> /S -- You received this message because you are subscribed to the Google Groups "Clojure" group.
