  "message": "gh-153772: Make abc isinstance() tolerate instances without __class__ (#154149)\n\nThe built-in isinstance() reads an instance\u0027s __class__ with a lookup that\nsuppresses AttributeError and falls back to the object\u0027s type, so\nisinstance(obj, int) returns False for an object whose __class__ access\nraises. ABCMeta.__instancecheck__ read __class__ directly instead, so\nisinstance(obj, Mapping) leaked that AttributeError.\n\nFall back to type(instance) when __class__ is unavailable, in both the C\nand the pure-Python implementations, so the abstract base classes behave\nlike the built-in isinstance(). Such objects are unusual, but they do turn\nup in the wild (for example some Qt widgets).",
