Guido van Rossum <gu...@python.org> added the comment:
Sounds like a plan, I agree that the original design misfired here (we were probably worried about million-line code bases with tens of thousands of classes having to pay the price of tens of thousands of empty dicts, but I now think that was an unnecessary worry -- that should be a few megabytes on a very much larger total). But given that you're not done yet: - Is it possible to create __annotations__ lazily? (IIRC in January we came to a conclusion about this, something like yes for modules but for classes, or the other way around?) - Why would __annotations__ ever be None? Why do you allow setting it to None? Do we know of people ever write '__annotations__ = None' in their class or write 'cls.__annotations__ = None'? - And where's your PR? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43901> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
