If that is the issue then we should be talking about non-space characters, not a 68 column limit right? No way does 40 spaces due to indent count towards the cognitive burden :) Also, if the cognitive burden is the issue then we should talk about short forms for keyword arguments again. The way the 68 column limit works in practice is that people avoid keyword arguments because of line length, plus the issues already mentioned. / Anders [Steve Barnes] If you are getting to 40 spaces of indent, (for _most_ people that is 10 scope changes, e.g. fn then 9 levels of if), then you are already facing a major cognitive burden and should probably be refactoring. _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
