[REBOL] Re: Rebol values (continuing the discusion)

Hi Ladislav, On Monday, April 18, 2005, 6:39:24 AM, you wrote: LM> There are two ways to prove you wrong.

So, as long as only one "1" exists, there still can be many representation of that one "1". REBOL integers are not numbers, but representation of numbers. So we can discuss of the numbers themselves, as you do, or we can discuss about their representations, as I did. I don't think one discussion should be considered "more true" ;-) than the other.

A notion: "distinct but identical" LM> illustrates well the trouble one gets into when using it. This problem goes away as soon as you say "two distinct representations of the same value". In the same way as you can consider that two strings can be not the same string even if they are equal, because they are two distinct representations of the same string. I agree that an "abstract", i.e. implementation-independent, description of REBOL is useful; however, only Carl could really provide us with something like that. Our conclusions are only based on the implementation, and other implementations are based on the conclusions we made on RT's implementation. Also, there are a number of issues that are interesting and that an implementation-independent description does not cover, such as how much memory does the block [1 1 1] consume? .
