Have you tried?
third object
(text from http://www.rebol.com/docs/core25.html)
You can use THIRD on the object to get back a block of set-word value pairs
from the object:
z: make object! [a: 99 b: does [a + 1]]
t: third z
== [a: 99 b: func [][a + 1]]
The block returned from THIRD on an object is like an object spec block,
however the set-words are bound to their object. This block is like a
snapshot of the object's values at that time. You can also use the returned
block to set values in the object:
set first t 199
z/b
== 200
