Metaprogramming in Ruby

Programming programs is fun! Programming programs to program other programs is even more fun! Sounds confusing? It doesn't have to be. With Ruby, metaprogramming becomes a thing of joy. In this talk we'll investigate:

* blocks, lambdas & yield
* eval, instance_eval, module_eval, class_eval
* const_set, const_get
* Class.new
* define_method
* method_added
* include, extend, and callbacks
* arity, parameters (1.9)
* ParseTree & ruby2ruby

We'll explore the capabilities and limitations of these techniques, exploring ways to create programs not typically possible. We'll use lots of practical examples so that you can follow along and learn how to use these techniques yourself!
