Sorry, my language there is imprecise. The chaining you get when an exception is raised during the handling of another exception is certainly useful during debugging, when the second exception is itself a bug. When I said "Exception chaining", I meant the specific form of exception chaining where you explicitly set the cause using "raise something from error". I don't object to people using that feature, but for me, it seems like a feature looking for a use-case. -- 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/3SFLPKZKAXSLDUAQX7JLBCZDETPQMBQX/ Code of Conduct: http://python.org/psf/codeofconduct/
