Hi,
While I would like to get such new attributes, I see drawbacks as blocker
issues and so I am fine with this PEP rejection. Performance is too
critical for most common exceptions.
For me one blocker issue is the high risk of creating reference cycles. And
the weak reference API isn't the most
The steering council felt the PEP was too broad and not focused enough.
Discussions about adding more attributes to built-in exceptions can
continue on the issue tracker on a per-exception basis (and obviously here
for any broader points, e.g. performance implications as I know that has
come up
