Many objects in the DOM implement custom name getters (for instance NodeList) and a few even implement custom name setters (CSSStyleDeclaration, at least the way it is done in WebKit) but no one has clamored for a custom deleter or expected delete to work "as a matter of consistency" or been confused that "style.opacity = 0" is allowed but "delete style.opacity" is not. So I would say the available evidence argues against your conclusions. Regards, Maciej
