Class

The class of classes. More accurately speaking, each class has its own unnamed "metaclass", and Class is the class of these metaclasses. This relationship is a little complicated, but it is not especially important to keep in mind while using Ruby.

Compared to modules, classes

• can create instances and

• cannot perform mix-in using include

Otherwise, nearly all of its capabilities are inherited from Module.

Superclass

• Module
