+0 This proposal may be worth re-considering. I've seen the problem arise in practice on multiple occasions. I suspect that it will continue to give people trouble. Right now, a bool is-a int that 1) only has two singleton instances equal to zero and one, 2) has a different repr, and 3) has the & | and ^ operations redefined to return instances of bool. I think we could also override the ~ operation. That would be a Liskov violation, making bools slightly less substitutable for ints, but it does so in a way that is intuitive and likely to match what a user intends when inverting a bool. ---------- nosy: +rhettinger, tim.peters status: closed -> open _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37831> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
