每个实例必须初始化其自身的缓存，但它只缓存那些它要使用的引用，并且可以直接访问引用而不是要到一个散列映射中去寻找。

A global variable is instantiated to its default value when it is first referenced in the session.
该特性比函数指针更强大，因为它允许内部类实例保持对创建它的环境的引用。
This feature is richer than function Pointers because it allows the inner class instance to retain a reference to the environment in which it was created.
隐式类装入发生在由于引用、实例化或继承导致装入类的时候(不是通过显式方法调用)。
