Thank you Allen for the references and analysis. It's interesting that Gilad argues resolution should be lexical followed by inheritance to avoid 'unanticipated name capture' that may exist within the inheritance chain. Probably even less of an option given backward compatibility requirements.

I realize there would be ambiguity for like named identifiers but that problem exists now... In Allen's first example this.handleClick(this,e) would not be resolved with it's implicit binding to elem, so 'this' would be bound lexically and the code would just work. The second 'this' would of course default to the implicit bindin
