meta-programming in ruby

最近大概是人生當中比較閒時段，拿起meta-programming in ruby 書本閱讀，思考rubyonrails可以幫助我什麼，它的核心精神又是什麼。rubyonrails一直是很magic framework，讓它這麼強大、動態原因還是在ruby meta-programming，隨手整理還需要強化的地方。

1. The object model
2. block (closure) v.s proc v.s lambda
3. methods (method_missing and dynamic methods)
4. class v.s module design
5. meta-program api
6. review of the design of activerecord

雖然ruby很動態、magic不過就像大老所說：

There is no such thing as meta-programming. It’s just programming all the way through.
