Expansion of existing introspection objects deemed acceptable •Consequence: • Severely limited: can’t do 3D with 2D abilities • No consensus on “how much” generation is just enough •No clarity on necessary primitivesWhere prototype implementation •Escapes inside a token sequence: • \( expr ) evaluates expr eagerly during creation of the token sequence • \id( e1, e2, ... ) concatenates strings and integrals, creates an identifier

这样子应该是可以打个基础了。 CCA.bbs@cis.nctu.edu.tw：函数名称可以查help，重要的是C++ 的观念。另外就是要了 解MFC 里的Document/View/Frame，以及Dynamic Creation, Message mapping 等等。 深入浅出MFC 第二版对这些部份都有很深入的探讨，把MFC 里的一些机制直接trace code 加以说明。 xv News / BBS 论坛（CompBook ）的实 作方式，亦尝试剖析其中与Windows 程序设计模型（注2）息息相关之特殊性质（注3）的 实作方式。 注1：此指runtime type information、dynamic creation、persistence、document/view¡ K。 注2：此指message based、event driven 之programming model。 注3：此指message 第四篇以微软公司附于Visual C++ 光盘片上的一个范例程序Scribble 为主轴，一步一步加 上新的功能。并在其间深入介绍Runtime Type Information（RTTI）、Dynamic Creation、 Persistence（Serialization）、Message Mapping、Command Routing 等核心技术。这些技术正 是其它书籍最缺乏的部份。此篇之最后数章则脱离Scribble
