Nick Coghlan added the comment: Having just said that I don't see much use for lazily initialized slots, it does occur to me that __weakref__ is essentially such a slot, and __dict__ itself could usefully be such a slot for types where instances mostly have a fixed set of attributes, but still allow for arbitrary additional attributes at runtime.
However, I do think any such proposal should be considered as its own issue, rather than being treated as part of this one - the assumed absence of the instance dict creates too many differences in the design trade-offs involved and the potential use cases. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21145> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
