Serhiy Storchaka added the comment: The more I think about this the more I like the idea of using int.__abs__() directly (PyLong_Type.tp_as_number->nb_absolute() in C). The C code doesn't call potentially overridable methods bit_length() and to_bytes(), it uses concrete implementations directly. I don't see reasons why it should obey overriding the __abs__() method.
This will save us from the problem with the wording of the error message. I mentioned a drawback, but the current implementation has the same drawback. We can avoid copying positive integer subtypes by using more complex code, but I think it isn't worth. ---------- versions: +Python 2.7, Python 3.6 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue31478> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
