@glitzersachen @loke @amszmidt PS: The reason I bring up the Roman Numeral thing might sound petty, but my reasoning is only this: For absolutely everything you can do in Lisp, if there is a practical opposite, you can do it with equal ease in a predictable manner that is reasonably similar. Except that one thing. You can convert one way with just a few additional characters, but you have to write a complete function to do its opposite that may ironically require the use of the same (format) to convert the input a second time.
I consider it a (very) minor inconsistency, but inconsistent it is. I won't be waving any flags over it at the next #lisp rally lol.
