Don't worry, Alan, we're writing software, not carving granite. Anything = can be changed, and I'm not out to get you! There seems to be some misunderstanding on both sides so let's clear = that up. It was far from obvious that your making `safe-copy-tree` a user-visible = utility arose from a particular need rather than just being easy to do = -- it wouldn't be the first time. If you really have a good reason to add safe-copy-tree then I'm = certainly not against it, but you haven't made much of a case for it. It = seems to have made its way in on the slip-stream of a bug fix. I found = no justification for it, so please forgive me for assuming there wasn't = any. The status quo is something everybody can agree is an improvement: a bug = has been fixed and that's it. Now if you want Emacs to come with a = standard circular tree copy function then it needs to go in on its own = merits: please argue why and how. Concrete examples would be useful. If added, your `safe-copy-tree` (wouldn't `copy-graph` be a more = accurate name?) should not be forced to share the implementation of what = is now `bytecomp--copy-tree`; that would just introduce unnecessary = compromises for either use. > would you please identify exactly what the bugs were. I only know that some of my (probably insufficient) tests failed for the = old implementation, for example ((a . #1=3D(b)) #1#) -- I didn't dig = deeper.
