Grab a scalpel as we put Ruby on the table to look at this lovely language's internals. We'll start with class inheritance and method lookup, and then explore the mysterious eigenclass and how it fits in. We'll use our newfound knowledge to turn children into zombies, meet unexpected vampires, and make our own Ruby mutants. Okay, so maybe it won't be too spooky, but you'll come away having a better understanding of Ruby objects and their internals (and braaaains!).
