WISH: set OBJECT from OBJECT

[Siskin-Bot]

Submitted by: Oldes

It would be nice to be able set all keys in existing object from another object.
Imagine to have:

spec: object [a: b: c: none]

and data object which may looks like:

data: object [x: 3 a: 1 y: none]

and you want to make object with only fields of the spec with possible values of data object.
In Red it is possible to use set:

>> set new: copy spec data  new
== make object! [
    a: 1
    b: none
    c: none
]

In R3 it now does this nonsense:

== make object! [
    a: make object! [
        x: 3
        a: 1
        y: none
    ]
    b: make object! [
        x: 3
        a: 1
        y: none
    ]
    c: make object! [
        x: 3
        a: 1
        y: none
    ]
]
