If I understand the problem correctly, these mis-attributions of roles (to 'data' instead of 'class' come about when a thing that is technically a class is defined in source using simple assignment, as with UnionType.

Problematic entries will thus have 'data' as role, and their identifiers will be camel-cased.

So, as a quick search to identify likely candidates:


>>> import re, sphobjinv as soi
>>> from pprint import pprint
>>> inv = soi.Inventory(url="https://docs.python.org/3.10/objects.inv")

# Find entries where the first character after the final period
# is uppercase, and the second character after the final period
# is lowercase.
>>> pat = re.compile(r"([.][A-Z][a-z])[^.]*$")

>>> pprint([obj.name for obj in inv.objects if obj.role == "data" and pat.search(obj.name)])

I would guess those 'ast.PyCF...' objects can be ignored, they appear to be constants?
