I think part of the issue is the idea that identifiers have attributes. In Python, identifiers are basically just labels in a namespace that bind to objects (and multiple labels can bind to the same object). Basically, in most cases the identifier is a key to a dictionary, the entry associated with it being a binding to an object. To add an 'attribute' to that identifier requires major changes in how that works and also will interfere with a namespace being able to override how that binding works. -- Richard Damon _______________________________________________ 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/ETOVSIZGVOIOCWGPGGV2X6IMO46PAI7O/ Code of Conduct: http://python.org/psf/codeofconduct/
