4.3.3 Creating Instances of Classes
The generic function make-instance creates and returns a new
instance of a class.
The object system provides several mechanisms for
specifying how a new instance is to be initialized. For example, it
is possible to specify the initial values for slots in newly created
either by giving arguments to make-instance or by
providing default initial values. Further initialization activities
can be performed by methods written for generic functions
part of the initialization protocol. The complete initialization
protocol is described in Section 7.1 Object Creation and Initialization.
