Josh Rosenberg added the comment: At some point someone really needs to decide if the C layer behavior of performing an identity test before full equality checking is something that should be emulated at the Python layer or not. The current state seems ridiculous, where C containers check identity first simply by using the easier RichCompareBool function, while Python containers have to have the identity-then-equality check rewritten explicitly, which feels like a DRY violation.
Makes it harder for non-CPython implementations too, since they end up either not matching CPython behavior, or writing extra code to match the CPython quirks. I have nothing against this patch, but between PyObject_RichCompareBool and the various slightly strange behaviors in the argument parsing format codes (which leads to silly workarounds like _check_int_field in #20858), I feel like the Python code base is getting cluttered with hacks to emulate the hacky C layer. ---------- nosy: +josh.r _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26915> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
