But we do believe that print-circle makes it possible to print out recursive structures, or? And we do not believe that it disturbs printing out non-recursive structures (except that it gets a bit slower), or? Could it make much harm then if we let describe-variable use it? And is it not a bug that Emacs hangs and eats all memory if you try to display a recursive structure with describe-variable?
