New submission from Eric V. Smith :
https://github.com/python/cpython/blob/3.8/Lib/types.py
The documentation says "If no callback is provided, it has the same effect as passing in lambda ns: ns."
I read this as saying that the callback should return the namespace, but in reality the return value is ignored. I think the lambda should be "lambda ns: None".
