My sense it that some folks think if we want late-bound defaults, we really should just do deferred objects. But I honestly don’t get it. My idea of a deferred object would be quite different that this, would not be a great replacement for this, and could quite happily co-exist with this idea. Clearly I’m missing something. So I think a paragraph or two explaining what is meant by defers objects, and how they’d be a better way to address late-bound defaults would be very helpful to the conversation. It's fine to criticize my inaction in advancing the more general idea.

So you have some obligation to explain. PEP 671 is very much the same. It does something worthwhile.
