[New-bugs-announce] [issue33207] typing.Generic does not correctly call super().__init_subclass__

[Will T]

New submission from Will T <timwilloney at gmail.com>:

Per the docs ( https://docs.python.org/3/reference/datamodel.html#object.__init_subclass__ ) this should be chain-calling super but currently doesn't, and thus breaks base classes listed after it which depend on this functionality. Attached a test for a real-world usecase of mine. Originally noted in https://bugs.python.org/issue32162? but on a new ticket as requested. Thanks :)
