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.

The differences Class has with Module are as follows:

• Class can create instances.
• Class cannot perform mix-in using include.

Besides that, nearly all of its functionality is inherited from Module.

Superclass

• Module
