The three facets of the class as a data type are its name, its relation to other classes, and the names of the slots that make up instances of the class. But you should generally use accessor functions or WITH-ACCESSORS unless you have a specific reason not to. Classes that represent the data types you've been learning about up until now, classes such as INTEGER , STRING , and LIST , are all built-in.

In this case, the applicable method will be one provided by the implementation, specialized on STANDARD-OBJECT.
