We probably do need better documentation for subclassing ExceptionGroup. When you subclass an ExceptionGroup you want to make sure that split() and subgroup() (which are used by except*) will continue working, usually by defining a derive() method: https://docs.python.org/3.11/library/exceptions.html#BaseExceptionGroup.derive If you don't define derive the superclass constructor is used, which means you get something of type ExceptionGroup, not your subclass. I don't know whether it's a good idea to make it easier to define a subclass that doesn't support split()/except* because ti changes the constructor signature without providing derive(). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46431> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
