Hi,
There has been request to add `Object.getOwnPropertyDescriptors` (plural) to
the standard. Reviewing use cases presented in thread [1] or in older thread
[2], it seems to me that all of them boil down to copy all own properties of
one object to another, e.g.,
Object.defineProperties(target, Object.getOwnPropertyDescriptors(source))
Object.create(proto, Object.getOwnPropertyDescriptors(source))
// etc.
However, this is exactly what `Object.mixin` (deferred from ES6) was designed
for:
Object.mixin(target, source)
Object.mixin(Object.create(proto), source)
// etc.
Besides being shorter to write, `Object.mixin` has the advantages of (1) not
creating an intermediate object; (2) taking care of some subtleties, like
rebinding `super` for methods, getters and setters if needed.
Therefore, I think that `Object.mixin` is a better function to have than
`Object.getOwnPropertyDescriptors`.
