When a new instance of a class is created by sending the message ':new' to an existing class, the message ':isnew' followed by whatever parameters were passed to the ':new' message is sent to the newly created object.

When a new class is created by sending the ':new' message to the object 'Class', an optional parameter may be specified indicating the superclass of the new class. If this parameter is omitted, the new class will be a subclass of 'Object'. A class inherits all instance variables, class variables, and methods from its super-class.
