(...) 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. Ciao -L
