The inability to pickle an object is not a feature, it is the lack of a feature. I think this is a case where PyPy initially did the right thing and then threw it away. I'm not satisfied by the arguments given here: http://peadrop.com/blog/2009/12/29/why-you-cannot-pickle-generators/ https://bugs.python.org/issue1092962 for CPython to not pickle generators, but pickling generators is not forbidden by the language, it is a quality of implementation issue. In this instance, both Stackless and PyPy 2 had better implementations than CPython. > I guess we could improve the error message to be more helpful. Do you > have a concrete use case for this? You have a generator which you are iterating through, and you want to stop your program and resume later. Or resume immediately but from another process. -- Steve _______________________________________________ pypy-dev mailing list pypy-dev@python.org https://mail.python.org/mailman/listinfo/pypy-dev
