The use cases shown in this video prove the operator is useful. But if you want it in the language you are missing the point. A few years ago, if you already knew one programming language and wanted to learn Python, you could just read 80 pages of Beazley's book and you'd know the language. There is enormous value in keeping a language small and 3.8 is exactly the release in which Python forgot this and started going downhill. Nobody wants loads of syntax to learn and none of the new syntax is needed. If these people did nothing, absolutely nothing, it would be better for the future of the language, than to keep adding syntax. If you want a huge language that takes months to learn, well, C# and Ruby already exist.
