It's consistent with what you do everywhere else in Ruby. The real metaprogramming is anything that involves a keyword. When you think about what that stuff does, it's really crazy. But since we're accustomed to it, we don't notice so much. I don't think metaprogramming adds that much overhead. Things like method_missing and const_missing are the ones that add actual overhead for me, because they're invisible when reflecting on the object. But defining methods doesn't seem crazy to me. The struct example I provided doesn't seem complex, you're just asking for a class with a specific set of methods, and a known initializer and set of behaviours. class_eval and instance_eval can also add complexity as things that seem like benign refactorings can break due to unexpected method lookups. Honestly, using modules to create large inheritance structures seems much more problematic to me. When the entire world is loaded into your environment, you can't think about one thing without thinking about everything. The overhead associated with this is tremendous, and for me greatly exceeds any pain I've felt from dynamically adding / responding to methods. -Josh
