(require mzlib/class100)

The class100 and class100* forms provide a syntax close to that of class and class* in Racket versions 100 through 103, but with the semantics of the current scheme/class-based class system. For a class defined with class100, keyword-based initialization arguments can be propagated to the superclass, but by-position arguments are not (i.e., the expansion of class100 to class always includes an init-rest clause).

The class100 form uses keywords (e.g., public) that are defined by the mzlib/class library, so typically scheme/class must be imported into any context that imports mzlib/class100.
