> it's got a canonical implementation

...until you realize that nearly every non-pg, non-rtm Arc user prefers to use the non-canonical Anarki, and recommends it because of the sheer number of bug fixes (never mind the new features, such as 'defcall, 'defm, 'p-m:, 'sync, 'thread-local, 'file-table ... etc.)

Yes, but Anarki's primary goal is still to keep fully compliant with canonical Arc (except for bugs, of course). Now, sure, there are the additions...

There's also the other problem with canonical Arc: pg has expressly stated that he will not retain backward compatibility between versions.

This also means that if Anarki tries to keep full compliance with ArcN in the future, without pg updating ArcN reasonably frequently, eventually (in a year? half a year?) Anarki will either: 1) die out as a source of innovation, because people will simply rather wait for pg's next update rather than push a change that might be overridden by pg in the future, or 2) drift so far away from pg's internal ArcN that when pg releases it, the merge hell will be very, very hot.

Take an example this: http://arclanguage.com/item?id=6138

  arc> (ssexpand 'foo?x)
  (is foo x)
Certainly I could implement that, and I think it's a good idea. The problem is pg's plans: does he intend a different meaning for #\? ? I don't dare to push this on Anarki, because if I do, I don't dare use it anyway, because pg might change its meaning in the future.

Edit: Ah, crick. I wish I can just say "Anarki promises to always keep compatibility with existing Anarki code. If pg breaks existing Anarki code in the next ArcN, we either (1) ignore the new feature, especially if we as a community feel that the existing Anarki feature is better, (2) rename pg's feature if possible, or (3) write a converter for old ArcN-1 based Anarki to ArcN based Anarki. Feel free to program in Anarki, where the magic carpet is assured of not being pulled out under you while you're exploring."
