I'd like to clear up some misconceptions here. (Filipp, this does not = mean that I think that you wrote something stupid -- quite the = contrary.)=20 First, is Emacs Lisp really simple? Yes and no. It's not easy to tell = where its boundaries are, especially since it doesn't have a proper = module or namespace system or a well-defined 'core language'. Basic = semantics -- control structures, built-in types, primitives and so on -- = are not too messy but definitely more than they need to be; Scheme it is = not. No wonder given its age; it has held up remarkably well = considering, but it would be even more remarkable if modern eyes could = not find flaws in it. Second, is simplicity paramount among concerns? Clearly not: = compatibility matters, and so does programming usability. It is also not = clear whether a change makes a language more or less simple; adding = bignums, for example, probably made the language less complex for the = user. Even if (hypothetically) people got by without `unwind-protect` by = catching and re-raising errors, few would object to adding that = construct as a special form because it made the language less simple. Of course you were talking about changes that make the language more = difficult to use, but my point is that it is far from clear what kind of = change actually does that. Unrelated to your comment: since several people have misunderstood the = proposal, I'm closing the bug to avoid conflating issues (I should have = listened to Stefan Kangas); a new one can be reopened for the patch at = hand when and if I get more free time.
