[Python-Dev] cls for metaclass?

[Pim Schellart]

Dear Python developers,

PEP 8 says:

"Always use self for the first argument to instance methods.

Always use cls for the first argument to class methods.”

But what about metaclasses?
PEP 3115 seems to suggest `cls`, and so do many Python books, however tools such as flake8 don’t seem to like it.
Is there a consensus opinion, and should PEP 8 be updated?

Kind regards,

Pim Schellart
