Example of modifying a builtin type: >>> class Sneaky: ... def __eq__(self, other): ... other['real'] = 42 ... >>> int.__dict__ == Sneaky() >>> (1).real 42 But it can also lead to crash (due to outdated type cache): >>> class Sneaky: ... def __eq__(self, other): ... other['bit_length'] = 42 ... >>> int.__dict__ == Sneaky() >>> (1).bit_length Segmentation fault (core dumped) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43838> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
