其他的面相对象编程的语言，没有提供这个指针。
Some other object-oriented programming languages do not provide that pointer.
正如其它范例当它们刚刚出现时(例如面相对象的软件开发)，由于它所包含的学习曲线，它需要经历一段时间以被广泛采用。
As did other paradigms when they were new (e.g., object-oriented software development), this one will take time to be adopted widely because it involves a learning curve.
NET语言中唯一提供多重继承和泛型的语言。正如在前面所讨论的，这两种功能对于采用真正面相对象方法开发完全可重用软件来说是必不可少的。
These two mechanisms, described in more detail elsewhere in this FAQ, are an indispensable aid to creating fully reusable software in a truly object-oriented way.
