Object.getOwnPropertyDescriptors(O) ? // plural

[Andrea Giammarchi]

You are right, I've realized it after posting ... `Object.assign(target,
source)` via `Get` and `Put` is basically the equivalent of a classic
`for/in` with `hasOwnProperty` check ... well, once again, in ES6
`Object.getOwnPropertyDescriptors(O)` seems to be a solution for other
cases too (shallow copy of properties, shallow clone, not just for/in) plus
yes, `Object.mixin(target, source)` might be simplified as well via this
proposal, that's a good point ... so 3 problems solved at once! :-)
