Which highlights another reason why I don't think there should be an
automatic implicit "self" - it "ennobles" one particular view of object
orientation.

You don't have to use objects in Lua - it's not just an OO language, and if
you do, you don't have to conform to a particular model of OO. This is a
good thing.
