Some minutes ago I found out that there is a mismatch between my interpretation of lazy-cats docstring and the actual behaviour of that macro.
Its docstring says: "Expands to code which yields a lazy sequence of the concatenation of the supplied colls. Each coll expr is not evaluated until it is needed." I would expect that in (take 0 (lazy-cat [(println 10)] [(println 20)])) no evaluation is needed. If lazy-cat were lazy it would return immediately, without concatenating anything. Maybe the docstring can get modified? Although I personally see this current behaviour as not correct, while the docstring is right. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
