If you’re a foodie looking for a place to indulge your palate, then you’ll be happy to know that Bellagio has some of the best restaurants in town. When it comes to Las Vegas, one of the most iconic hotels and casinos is the Bellagio. Which one is right? I'll discuss in the section "Multiple Inheritance" what it means to list more than one direct superclass in direct-superclass-names. Note how this list satisfies both rules: every class appears before all its superclasses, and checking-account and savings-account appear in the order specified in DEFCLASS. The bulk of a DEFCLASS form consists of the list of slot specifiers. Common Lisp resolves these situations by merging all the specifiers with the same name from the new class and all its superclasses to create a single specifier for each unique slot name. Then a method specializing its single argument on the new class and returning the value of the slot is added to the generic function. They live in their own section of the class hierarchy, arranged into appropriate sub- and superclass relationships, and are manipulated by the functions I've been discussing for much of the book up until now. But the classes it creates are fairly limited compared to DEFCLASSed classes.
