I don't agree. Cooperative multitasking looks quite orthogonal to me to the complexity brought by this new statement. You can perfectly well "grasp the concepts of cooperative multitasking" without finding the semantics of this new statement easy to understand and remember. Hiding so many special cases behind a one-line statement does not help, IMO. And providing a commented version of the expansion does not really help either: it does not make the expansion easier to remember and replay in the case you have to debug something involving such a "yield from" statement. (remember, by the way, that a third-party package like greenlets already provides cooperative multitasking without any syntax addition, and that libraries like Twisted already have their own generator-based solution for cooperative multitasking, which AFAIR no one demonstrated would be improved by the new statement. I'm not sure where the urgency is, and I don't see any compelling use case.) _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
