The examples shown seem to create the very problem you claim traits solve. It is only the introduction of your `impl` keyword in the example that allowed there to be more than one `x()` in the first place. Can you elaborate on why this is even a problem in the first place that would need solved in Python code today? > _______________________________________________ > 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/KFTJ6QRCTICL4NDUURNY35D7JIDM3VWY/ > Code of Conduct: http://python.org/psf/codeofconduct/ -- CALVIN SPEALMAN SENIOR QUALITY ENGINEER cspea...@redhat.com M: +1.336.210.5107 TRIED.
