FWIW, I totally agree. Expressions like that are extremely confusing, and it is surprising that they are valid. Real-wold usage of those is more likely to be accidental than purposeful, so it would be better if they were disallowed and treated as syntax errors. -- Steve J. _______________________________________________ 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/GV6BKGW4MRNCKEVL7R75JFD7KRALNJRH/ Code of Conduct: http://python.org/psf/codeofconduct/
