[New-bugs-announce] [issue43815] documentation for types.new_class() mention misleading default for exec_body

[Eric V. Smith]

New submission from Eric V. Smith <eric at trueblade.com>:

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".
