> classes in Racket are themselves *runtime* values Thank you. Now I understand. I don't remember any language with classes, except Racket with such feature.
Usually, either a class is a type, so it is defined in compile-time, or there no classes at all and objects just built on a prototype. In Racket any type is a struct, but class is not a struct.
