Message280657
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. |
