Aside from the use of "hasOwnProperty" as an instance method in Crock's original example, which he elsewhere shows how to correct, Crock's "registry" is used correctly. Together with the proposed __proto__ as accessor behavior, Crock's code would actually be correct (though I'd still advise using an abstraction like StringMap that can encapsulate such hazards and present a simple interface). -- Cheers, --MarkM
