Looks like a separate issue to me. That issue can be fixed by updating the Python implementation of WeakKeyDictioary.
The fix for the WeakKeyDictionary issue I mentioned and the Ephemeron primitive (as Sebastian identified it) are equivalant (you can implement one from the other) and cannot be reduced to any existing primitive as far as I can tell. Such a change would need to happen within the Python engine itself. _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/KJUFOKVTU2YY32CS6TCRAN3P3XLBCJ42/ Code of Conduct: http://python.org/psf/codeofconduct/
