A more concrete use case might help make the argument better. My first thought was a function that needs the zero value for a set of (ints, floats, polynomials, whatever) could just do elements[0], but how often does that come up? (And how often can you trust that the type’s zero value is ==0, but can’t trust that the nullary constructor returns a zero?) I’m pretty sure I have run into a handful of more useful uses for this method over the years, but I can’t remember any. Maybe something to do with Unicode normalization? _______________________________________________ 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/FFHOCSF4RDJIEBPRPNGC3AVIODYAVRFB/ Code of Conduct: http://python.org/psf/codeofconduct/
