I actually think next is pretty close to the next method on Java iterators. In java.util.Iterator, the next method evaluates the next item, increments state the iterator, then returns the evaluated item. In Clojure, the next function evaluates the next time, then returns a cons containing the evaluated item and the Clojure equivalent of an incremented iterator. It's essentially the functional equivalent of the Java method. Regarding Lispers, Clojure already differs from common Lisp in that nil != (). I think the proposed lazier changes make rest more consistant; instead of returning a collection or nil, it just returns a collection. Philosophically, I think this is closer to the idea of a cons cell than it was previously. Of course, this is all just my opinion :) - James --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
