I like this idea. It is similar to how Jython and IronPython object IDs work: # Jython >>> id(None) 2 >>> id(len) 3 >>> object() <object object at 0x4> > I do not propose to use serial numbers for all objects, because it would > increase the size of objects and the fixed-size integer can be > overflowed for some short-living objects created in mass (like numbers, > strings, tuples).

This sounds reasonable to me. +1 -- Steven _______________________________________________ Python-Dev mailing list -- [email protected] To unsubscribe send an email to [email protected] https://mail.python.org/mailman3/lists/python-dev.python.org/ Message archived at https://mail.python.org/archives/list/[email protected]/message/PDN2DF3BTU4P3N5MD5GEHUZRAT6ETGU5/ Code of Conduct: http://python.org/psf/codeofconduct/
