[REBOL] Re: On mutability and sameness

From: robbo1mark:aol at: 21-Jun-2001 5:27

JOEL, The point is that Ladislave, yourself & others debated at length, trying to use only REBOL and a natural language ( English ) to demonstrate the differences in property & behaviour of SAME? & EQUAL? functions. Using REBOL was insufficient in producing a function for testing whether an any-string! or any-block! value shared the same memory location, and natural language was to ambiguous and lead to discussions about concise definitions & meanings for words. Your use of C, whilst admittedly not making it clear to everyone, showed demonstrably the why & how of the different behaviour. Anyone who knows C could study your example and see the logic that produced the REBOL like behaviour. This lead me to a quicker and more precise understanding than the previous "higher level" attempts at explanation did. It depends on what your goals are, my goal was understanding the behaviour, perhaps Ladislav & yourself are looking to "describe" the behaviour more CONCISELY. The use of C helped my understanding, but whether it aided your attempts at CONCISE explanation, that is for you and others to decide, all I can say is you helped me to clarify my understanding and I thank you for that. With regards to REBOL being open source, it isn't and I accepted that a long time ago too! It's a shame it isn't because that would help me further my understanding enormously being able to study the sources, but it's NOT and so I & others have to formulate our own model of understanding & possible implemetation, which is *FUN*, so that is what I do, if I can learn & share from and with the help others, great! hopefully we all benefit from the process. I love REBOL and will continue to use it and learn from it, it is a wonderful productivity tool, that doesn't mean I accept proprietary technology as a good thing or think that the implications & consequences of it are desirable, IMHO they're not, but I won't expound that view here. All I will say is how advanced would our understanding of modern science be if the discoveries of Newton, Einstein, Planck, Maxwell etc. were proprietary & secret? Thank you for helping me further my understanding. Mark Dickson In a message dated Wed, 20 Jun 2001 4:18:39 PM Eastern Daylight Time, Joel Neely <[joel--neely--fedex--com]> writes: << Hello, all!

I knew better at the time, but haste overruled common sense. I hereby apologize to one and all for using the "c" word. If I promise never to do it again, will you let me forget that I did so? ;-) -jn- -- It's turtles all the way down! joel'dot'neely'at'fedex'dot'com
