The PEP 670 lists many pitfalls affecting existing macros. Some pitfalls are already worked around in the current implementations, but the point is that it's easy to miss pitfalls when reviewing code adding new macros or modifying macros. Erlend did an analysis in: https://bugs.python.org/issue43502 For macros reusing arguments (known as "Duplication of side effects" in GCC Macro Pitfalls), see his list: https://bugs.python.org/file49877/macros-that-reuse-args.txt Victor _______________________________________________ Python-Dev mailing list -- python-dev@python.org To unsubscribe send an email to python-dev-le...@python.org https://mail.python.org/mailman3/lists/python-dev.python.org/ Message archived at https://mail.python.org/archives/list/python-dev@python.org/message/25RWEFLDPP7I7Y7DUT75YBRVMMSNN5QI/ Code of Conduct: http://python.org/psf/codeofconduct/
