Thanks for the work you are doing on this PEP and for debunking my misconceptions regarding types, I’m currently learning a lot about them. I don’t know if it matters but I’m in favor of the method > And to those who support this PEP, code examples where a dict merge > operator will help are most welcome! Not matter the notation you end up choosing, I think this code: https://github.com/jpadilla/pyjwt/blob/master/jwt/utils.py#L71-L81 which is part of a widely used library to validate JWTs would greatly benefit from a new merge to merge dicts.
