Lists of symbols are Lisp object, are perfectly readable, but shouldn't use `read--expression'. `read--expression' is to read the subset of S-exps which represent an Elisp expression (something that would be meaningful to pass to `eval', for example). > Why isn't `read--expression' treated as a user function, like > `read-minibuffer', instead of being considered "internal"? Can't remember the details, but I think it's because it's easier to make it "external" than the reverse. > And `read-minibuffer' is still used for `interactive' with > spec "x". Why isn't `read--expression' used for that now? Not sure either. Probably just a conservative choice. Stefan
