This can be noticeable and potentially problematic on large projects , especially since the crosscutting nature of aspect - oriented dependencies often means that a large part of the system needs to be recompiled when a pointcut changes 在大型项目中，这些开销有可能是很可观的，而且可能带来一些问题，特别是面向方面编程的横切特性通常意味着，在切入点发生变化时，大部分系统都需要重新编译。
His time is divided between developing tools and technology to support aspect - oriented programming , helping groups inside and outside of ibm to adopt and apply the ideas behind aop , and writing and speaking on the theme of aspect - oriented software development 他的时间分成：开发支持面向方面编程（ aop ）的工具和技术，帮助ibm内部和外部的群体采用和应用aop背后的理念，以及编写和演讲关于面向方面软件开发的主题。
Currently , the aop is still during the evolution . the aop languages and implementations are imperfect , but the appearance of the aop may change the whole way of developing software . it could implement the “ use case - drive ” developing more perfectly 作为其它编程思想的补充,面向方面的编程思想还在不断发展中,虽然当前各种面向方面语言和面向方面的系统都还存在着不足,但是面向方面编程思想的出现仍有可能改变整个软件开发的方式,使得程序员更完美实现“用例驱动”的方法开发软件。
