About "absolute sameness":
1) My goal was to find a "natural" definition of identity in Rebol.
2) You are free to write your own definition if you like, but I am pretty
sure, that you will have big problems with the "absolute sameness". The
reason is simple: my definition is the finest equivalence you can define in
Rebol, therefore any definition you can write either cannot be finer then
mine, or it cannot be an equivalence. No sameness that isn't an equivalence
can be natural, neither I think, that any coarser equivalence is a true
identity.
