I'm not convinced that this is better, because it would make value-returning something specific to generators. On the other hand, raising StopIteration(value) is something that any iterator can easily do, whether it's implemented as a generator, a Python class, a C type, or whatever. Besides, it doesn't smell right to me -- sort of like returning a value from a function by storing it in a global rather than using a return statement. -- Greg Ewing, Computer Science Dept, +--------------------------------------+ University of Canterbury, | A citizen of NewZealandCorp, a | Christchurch, New Zealand | wholly-owned subsidiary of USA Inc. | [EMAIL PROTECTED] +--------------------------------------+ _______________________________________________ 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
