Ah, yes. Thank you. So it works in CPython 2.7. But I'm curious, does it work in very old versions? I'm not saying that this is important, because language changes always are for new versions. However, Anders' claim that this not a language change seemed too broad to me. It may be that this change has very little cost, but it should not be dismissed.
It works in:
Python 1 Python 2 Python 3 PyPy 6 IronPython Jython micropython
Are there more I should try?
I've no idea what you actually tried or what actually worked, since you haven't shown your code.
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. I have said so many times.
, and it makes no difference how many implementations are lax enough to permit it currently.
Sure it does. See above.
You can show millions, billions, trillions of examples that support your assumption, but that doesn't make any difference - the assumption is false as soon as there is a single counter-example,
...which there isn't. But that's irrelevant. We both agree it's irrelevant.
or as soon as the specification is shown to *permit* a counter-example.
Maybe. 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.
