I understand that we are trying to avoid adding keywords but could `implement` or a synonym work? If you override something that your superclass implements then you wouldn't need the `implement` keyword, just `override`. This has the benefit of making it clear that the method came from a protocol and not a superclass.

The discussion is pretty dead right now, but the key point is that override would only be used when replacing another required implementation member, not when just conforming by implementing a required member.
