I agree that nobody will use an inherited 'value' property, however
Yeah, that fails anyway and if you loop through a for/in and attach as own
property you are moving the problem instead of actually solving it in the
current state of the specs.
This is probably closer to what I meant by `Descriptor` solution to improve
reliability of descriptors in possibly hostil

Oops, misfire. The rest of that:
function shadow(obj, props) {
var ret = Object.create(obj);
for (var k in props)
ret[k] = props[k]
return ret;
}
// Elsewhere...

pretty confident nothing will break 'cause own properties is what

This would already fix the `Object.prototype.get` or `.set` case since I
