6.7 Class types

A class refers to a type or a value depending on its use.

class A 
{
    static var x
    var y
    prototype var z
}
var a : A  // A means type A
a = new A  // A means value A

The value is a class object that has the form shown in the drawing above. The class object is CA. When used as a type, it evaluates to its instance traits (TA). When used in a new expression, the class serves as a factory object with a special method that creates a new instance (OA), which contains an internal delegate property pointing to the class object's prototype (P) and an internal traits property pointing to the class object's instance traits (TA).
