But it does accept functions, as that piece of code shows, so the sharp quote syntax is even more confusing/tedious/error-prone as it separates functions from symbols, only that shouldn't always be done, as it depends on the function that gets the symbols (or functions as symbols) as well! It is very much to think about compared to just typing: ;; enable commands (put 'upcase-region 'disabled nil) (put 'downcase-region 'disabled nil) (put 'erase-buffer 'disabled nil) (put 'suspend-frame 'disabled t ) Here, everyone immediately understands that `upcase-region' is a function and that isn't disabled anymore. The special syntax for functions, which shouldn't even be used, would, if used, not clarify that one bit in my eyes/fingers. > The thing is that the implementation of those > "notions" or "data abstractions" that are _symbols_, > _functions_ and _function designator_ can, did, and > will change, across time and space (space being > different lisp implementations). > > On the other hand, the "functional abstractions" > such as put don't change. I never worry what will happen. When it does, I'll make it work, then. People always tells me my code will break, but it never did. Or maybe it did and I fixed it, I don't know. -- underground experts united http://user.it.uu.se/~embe8573
