AFAIK there is existing issue for this idea. I have doubts about performance. I added _PyObject_LookupAttr in particularly to avoid an overhead of raising and silencing an AttributeError. I believe most performance sensitive code in the core now uses it and will not be affected, but there is other code which silences it (_PyObject_LookupAttr itself silences an AttributeError raised in called functions), third-party code which uses PyObject_HasAttr or PyObject_GetAttr can be affected. It might be simpler to implement it in sys.excepthook or sys.displayhook, but at that point we do not have attribute name and a reference to the object. There is an issues and a PEP about adding references to AttributeError. It could help to implement this feature. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38530> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
