PEP 473 was recently rejected (https://mail.python.org/pipermail/python-dev/2019-March/156692.html) because it was too broad and was suggested to be broken down in smaller issues.

This issue is requesting the addition of the optional attribute `name` to `NameError`.

The idea of having a structured attribute is to allow tools to act upon these exceptions. For example you could imagine a test runner which detect typos and suggests the right name to use.

There is a current PR (https://github.com/python/cpython/pull/6271) adding this functionality, but it may need to be rebased as it has been awaiting a reply since April last year.
