There would be tremendous wasted >effort with not much gain. it might suprise you to know that most of the major vendors are represented on the committee (BIM, SICSTUS, QUINTUS, IF, IBM and others that don't readily come to mind, but don't be insulted :-). it will be really suprising if the final standard isn't exactly what these people want. of course what vendors want is not necessarily what users want. but that's another issue. >So the effect could well turn out to be that vendors go on providing >more or less the old version (with perhaps a few useful extensions) >and that would remain the DE FACTO standard, making the official >standard nothing more than an academic curiosity. with this many vendors behind it, i would be suprised if they don't back the standard. it's in their own interest. >I have not read the latest version of the new standard, but >Richard's quotations and comments leave me feeling that it is likely >to diverge far too much from the existing widely "agreed" de facto >standard, and, as he points out, would break too much code. it is inevitable that some code will be broken just in trying to resolve differences between similar, but nonetheless not identical vendor's products. what do you expect? -gerald p.s. richard o'keefe is a contributer to WG17 by the fact that he posts constructive discussion on the net where he knows WG17 people are listening (reading?). since he knows they have thick skins, he doesn't worry about expressing his opinions in his unique style :-) p.p.s. anyone can contribute to WG17 just send in your opinion!
