— class option: #:metaclass metaclass

The #:metaclass class option specifies the metaclass of the class being defined. metaclass must be a class that inherits from <class>. For the use of metaclasses, see Metaobjects and the Metaobject Protocol and Terminology.

If the #:metaclass option is absent, GOOPS reuses or constructs a metaclass for the new class by calling ensure-metaclass (see ensure-metaclass).

— class option: #:name name

The #:name class option specifies the new class's name. This name is used to identify the class whenever related objects - the class itself, its instances and its subclasses - are printed.

If the #:name option is absent, GOOPS uses the first argument to define-class as the class name.
