Please take a deep breath. The question was not directed at you and I just answered a clear and simply stated question. All the examples cited, including the one you link to below work. No need to get angry about this. If you are upset if I discuss implementation details don't reply. This is all I'm doing at this point. > However, it doesn't matter. Of course it matters. It's the difference between changing the spec and changing the spec AND some implementation. There is a difference between those two things. You might not care but that's another topic. > This IS a > language change Yes I agree.

But I haven't argued that this implementation detail is already in the spec have I? I have just argued that it's easy to IMPLEMENT because it is in fact already implemented in all existing pythons. I don't see why this is such a hard concept for you to grasp. Yes I know it would be a change to the spec. I have conceded this point MANY TIMES. You don't need to argue that point, you've already won it. By walk over even because I never argued against it. Can we drop this now? Your point has been made. / Anders _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
