What if a default is a function? I was inspired by learning Django and saw in models that fields can have a default which is either a regular (early-bound) default such as a first-class Python object as one would expect, *or* a function -- which will be called 'later' when needed. That prompted me to contemplate a syntax for late-bound defaults, albeit a bit clunky, but I did think it suited a special-case requirement met by late-bound defaults. I still think that littering function arguments throughout all code with large numbers of arrows would make things less readable. Special requirements need special treatment, I'm thinking. The problem is passing arguments to such a function without it looking like it's being called at definition time. _______________________________________________ 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/PJNVHV3UY5L67GDEZWGXMRPIL6SN4563/ Code of Conduct: http://python.org/psf/codeofconduct/
