I will follow the PEP evolution more close now. And indeed, as we can see, even in a case like this in the thread, where the "+" could have been useful (1) the OP did not think of using it at all, coming up with a different approach, and (2) the exiting star-map expansion can do what "+" would do in this case. These would point to that maybe it is not "necessary" at all. Although I still think it would be a useful feature, and, on that, maybe keeping the consistence with the "|" already in use by 'set' would be better. > > -- > 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/OHKUFD4IU5IJTUPP2GKE2TGHSAORXL7C/ > Code of Conduct: http://python.org/psf/codeofconduct/ >
