As I said tweaking `format` to work on rationals could be too much, and i can restate that as "it is too much".
Nevertheless, extending it to work on bigint doesn't seem to me really an edge case, given that i could get a bigint out of any function that uses autopromotion, so: (printf "%d" (autopromoting-factorial N)) would work only for small enough inputs. That's a bit surprising, so i keep my +1 while I learn cl-format. Then, if cl-format, is the "true" formatting function for clojure, why isn't it in core?
