Possibly not. But the beauty of a protocol is that it can work even if the object doesn't define a `__view__` dunder. - If the object defines `__view__`, call it; this allows objects to return an optimized view, if it makes sense to them; e.g. bytes might simply return a memoryview. - If not, fall back on a generic view object that just does index arithmetic and delegation. -- Steven _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/4R5CRI2MJP3R4PZPDRTDZFYOCDPSP3I2/ Code of Conduct: http://python.org/psf/codeofconduct/
