The above statements only serve to prove my point. I reiterate: What we are talking about is NOT a minor feature. If *nix platforms had no command line, you would implement the needed connections in whatever way required. Macs do things differently. So what! They require a different kind of implementation, i.e., AppleScript. So what! That is the way it is done on a Mac. And despite the fact that OS X (*nix based) does have a command line, it STILL uses apple events and AppleScript. AppleScript will continue to be the way such things are done on the Mac platform, by all but the most die-hard. Your complaint that you haven't made Rebol 'the same' on the Mac because 'the Mac is different' is at best weak and certainly leaves Rebol's cross-platform and "universal" claims ringing quite hollow indeed. In short, what you are saying is: "Rebol is universal and cross-platform, except on the Mac, because on the Mac it is inconvenient." Depending on whose statistics you like to use, the Mac holds from 5% to 10% of the computer market. It is reasonable to assume, since a disproportionately high percentage of web sites are served from Macs, and because Rebol is a network-centric language, that interest in Rebol on the part of Mac users would at the very least parallel the Mac's market share. Which means that at least 5% of the people subscribed to this list ought to be Mac users or at least Mac-centric. Based on what I've seen so far in the way of responses, I'll bet the figure is substantially lower. In fact I wouldn't be surprised to find that I'm the only one, or one of only two or three. If I'm right, then you have already lost your battle to become a universal/cross-platform language, because one of those platforms, at your own insistence, has chosen to ignore you! Do I think Rebol is better than Perl and other languages? Absolutely, and by a wide margin. Is the concept of Rebol brilliant? Is Carl Sassenrath a genius? Unequivocally. Will I be using Rebol? No... the people who make Rebol don't think it is important to make Rebol useful to me because I want to use it on a platform that is non-conforming. While the concept of Rebol is visionary, at least this one aspect of its implementation is not, which I believe dooms Rebol to end up on the scrap heap with the HUNDREDS of OTHER brilliant, visionary new languages already there.
