Just to be clear, mutating the class object was never the point for my main use case that needs the PEP 422 feature; it was for method overloads that are called remotely and need to be registered elsewhere. For some of my other use cases, adding metadata to the class is a convenient way to do things, but classes are generally weak-referenceable so the add-on data can be (and often is) stored in a weak-key dictionary rather than placed directly on the class. _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
