Lisp与编程范例

没事看到Lisp教程，尽管作者鼓吹它多么amazing，看完之后我觉得实在是非常简单的语言。
主要介绍了递归和高阶的应用，递归就不说了，高阶（high-order)说白了就是函数能当参数用，其实没不稀奇，java里不都有回调函数么。
其实也不意外，48年历史的语言，那么古老的东西，能有多厉害？

Lisp作为函数式语言(functional program language),顺便学习了一下wiki里所谓的编程范例（programing paradigm）。
编程范例可是个重要的概念， 所谓编程范例其实就是编程的一种风格，一种如何思考并解决问题的思想模式。
一般一种编程语言支持一种以上的编程范例，以c++为例，支持过程式，OO，命令式，泛型等编程范例。
支持的多并不一定好，很多人用java/c++写的都是过程化思维的代码。如果java只支持OOP，我看未必不是一件坏事。
大约在一年多以前，我老是搞不清自己什么时候在用什么范例思考问题。
用户描述问题的时候，往往是工作流思维，BA写的文档往往是数据流处理的思维，然后我用java写出来的也往往是过程化思维的代码。
OO大师鼓吹OO是符合人性的思维，但是实际上一旦涉及到软件系统，往往连用户都变得很专业，他们会抛弃原有的OO思想，“数据库”，“表”，“数据”这些专业词汇都是从
他们口中冒出来，于是很难从需求分析开始以OO的思维考虑问题了。
老板也会给你一个过程化思维的文档模板，要求你为项目补写文档。


附常见范例：

• Annotative programming (as in Flare language)
• Aspect-oriented programming (as in AspectJ)
• Attribute-Oriented Programming (as in Java 5 Annotations, pre-processed by the XDoclet class; C# Attributes)
• Class-based programming, compared to Prototype-based programming (within the context of object-oriented programming)
• Concept-oriented programming is based on using concepts as the main programming construct.
• Constraint programming, compared to Logic programming
• Dataflow programming (as in Spreadsheets)
• Flow-driven programming, compared to Event-driven programming
• Functional programming
• Imperative programming, compared to Declarative programming
• Logic programming (as in Mathematica)
• Message passing programming, compared to Imperative programming
• Object-Oriented Programming (as in Smalltalk)
• Pipeline Programming (as in the UNIX command line)
• Policy-based programming
• Procedural programming, compared to Functional programming
• Process oriented programming a parallel programming model.
• Recursive programming, compared to Iterative programming
• Reflective programming
• Scalar programming, compared to Array programming
• Component-oriented programming (as in OLE)
• Structured programming, compared to Unstructured programming
• Subject-oriented programming
• Tree programming
• Value-level programming, compared to Function-level programming
