Being able to choose between one desirable behaviour and one undesirable, rejected behaviour is *not* a strength. PEP 505 has a section explaining why catching AttributeError is undesirable. I find the reasons it gives are compelling. Can you explain why you reject the PEP's arguments against catching AttributeError? -- Steve _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
