Ever wonder just how Rails declarations such as "has many" and "belongs_to" work? Ever wished you could write your own code that worked the same way? It turns out that this style of programming, often called metaprogramming, is easier than you might think. In this talk we'll see how Ruby's open classes, compile-time execution, and full meta-object model make it easy to write your own extensions.

Good presentation by Dave Thomas. Very entertaining. It clearly demonstrates why Ruby won't be able to make it to the masses.
