Eigen What Now?

Eliza de Jager // @code_kitten


Eigenclasses are an important construct in Ruby and, although obscured from the everyday developer, are core to many meta-programming principles and techniques.

We delve into what an eigenclass is, how to access it, and how to make use of this knowledge in order to improve our meta-programming techniques. Method lookup, singleton methods, class_eval and instance_eval, and include and extend will all be explained in the context of eigenclasses.
