BaseException seems, well, wrong to me, and arguably less informational (or worse, misinformational). Why not just improve the error message in the (presumably existing) ModuleNotFoundError? Or create a specialized CursesNotFoundError derived from ModuleNotFoundError? _______________________________________________ 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/M2UI5LR5ADOOBOBLTIEQ2VOUXY7LYGFO/ Code of Conduct: http://python.org/psf/codeofconduct/
