Subject: bpo-38291: Fix a spurious warning when using help(object) (#27039)
X-Git-Tag: v3.11.0a1~724

bpo-38291: Fix a spurious warning when using help(object) (#27039)

help(object) via pydoc.TextDoc.docclass(object) iterates over the
subclasses of object, which includes typing.io and typing.re if typing
is imported. It tries to access cls.__module__ for each of those
sub-classes. This change suppresses warnings when accessing
cls.__module__.
