…olean unsafe_hash. (pythonGH-5891) unsafe_hash=False is now the default. It is the same behavior as the old hash=None parameter. unsafe_hash=True will try to add __hash__. If it already exists, TypeError is raised. (cherry picked from commit dbf9cff) Co-authored-by: Eric V. Smith <ericvsmith@users.noreply.github.com>
