Not in the references he supplied (or, at least, not in the Java one). There, a Future is a proxy object, whose actual characteristics will (or may) be filled in later. If you need it, you wait for it, but if you don't need it yet, it can be created in the background. How to make this cleaner than the existing concrete implementations (such as a twisted Deferred, or spawning a thread which puts a return value in a known location) -- that is the part which hasn't been worked out. -jJ _______________________________________________ Python-3000 mailing list Python-3000@python.org http://mail.python.org/mailman/listinfo/python-3000 Unsubscribe: http://mail.python.org/mailman/options/python-3000/archive%40mail-archive.com
