(In reply to comment #29)
What do you mean by "isn't possible currently with
interfaces-implemented-by-JS"?  In JavaScript, this is a property existence
test that can be performed using Object.prototype.hasOwnProperty or
Object.getOwnProperty.  This exact pattern is used quite extensively by the ES5
Object.defineProperty to process its "options parameter".

Are you saying that host object interfacing layers in browser don't provide the
capability for such tests or is something else the issue?
